Is it me, or are there major issues with iTunes update 10.4.0.80?

I'm having also troubles since I've upgraded to Itunes 10.4 . My computer turn on Vista 32 bits

When I tried to sync 20 videos to an iPad2, iTunes started to use lot of CPU and afer 20 minutes it crashed.

If I try to sync the videos 1 by 1, it works.

The same problem from other perspective: if I try to sync a big video optimized for iPad2 (2 GB), iTunes always crashes. The same video was synchronized with no problem with previous version of ITunes.

I'm also getting the same problem, ever since my upgrade yesterday I'm unable to use the play/pause, next/previous track buttons on my keyboard and only get a solid black box when I add cover art.

Me, can't access to iTunes these 2 days!!! "Can't connect to iTunes", that's the pop up message that i've been receiving. What's the problem?

I Did not update software recently. Just out of sudden can't access to iTunes from iPad!

I ended up uninstalling and reinstalling iTunes using the order specified in Apple's support document. That did not fix the crashes I was getting when syncing media with my iPad 2. I ended up calling Apple and they had me do a complete restore of my iPad 2 and setting it up as a new user. At that point I successfully synced all my data (except photos which I didn't try). I then restored the backup data and settings. After that iTunes immediately tried to sync and made it all the way to the "optimizing photos" stage where it promptly crashed. I tried removing the iPod Photo cache folder, but that just caused iTunes to try and re-optimize all my photos and it ended up crashing at about 2450 out of 1600.

The only way I could get iTunes to sync without crashing was to delete the new photos I added and then sync one album at a time.

I'm still noticing much higher than normal CPU usage when syncing music and podcasts since restoring my iPad backup data, though I haven't seen it crash on music or podcasts yet. I have a feeling it will crash again if I try to add a new photo.

At this point, it looks like the "fix" is to either do a restore on my iPad 2 and not restore from the backup data (not something I want to do) as there is apparently a setting on my iPad 2 that iTunes 10.4 does not like or revert back to iTunes 10.3.1 (not sure if that will work or not).

Either way, iTunes 10.4.0.80 is garbage since I never had any problems syncing under 10.3.1 or earlier.

For those interested, to downgrade back to iTunes 10.3.1, you need to either have saved the install file for it or find a copy of it out on the net.

At that point you can follow the instructions for downgrading on this page (even though it's for iTunes 10.5 beta, the steps should be the same.

I too am having issues with itunes... works fine on my iphone but not on my computer.. i try to log in and all it does is accessing itunes store and thats it.. i cant log in or sync my ipod..

Yo Diesel dude... speak for yourself... there seems to be thousands of reported issues... but somehow you're a special case.

I also have had major identical issues on 2 different XP systems after the upgrade to 10.4.

Yup I lost access to the iTunes store. Now everything else works. I can even update Genius. I'm running Windows 7, 64 bit version. My iPhone 4 and iPad 2 have no problem accessing the iTunes store.

Looks like there are several discussion threads runnig that are covering this same issue, so I am posting here as well hoping that Apple will at least look at one of these.

I'm getting the same error as the original entry when trying to sync with my ipad. As stated above, this all happened after doing the 10.4 upgrade. The 10.3 version of iTunes worked just fine. I don't know if this makes any difference, but I'm running iTunes on a PC running Windows 7. I did some investigation and found that what seem to be causing the sync crash on my system is some movies that I took and originally copied over with my pictures in version 10.3. These home movies are .mov file extension files and if I remove them from my photo sync folder, leaving just the .jpg files, the sync works just fine. Any suggestions or a new version of iTunes which works as well as 10.3 would be great...

PS. I tried to go back to iTunes 10.3 but 10.4 changed something in the library file which stops 10.3 from being able to read it, so looks like I'm stuck..

I think my issue is tied to the videos as well. I'm running Win 7 64 bit & have uninstalled itunes and reinstalled it with no luck. By trial and error I did get it to sync when I unchecked sync videos. Now, I need to determine which video it is or if it is all of them. Have spent WAY TOO MUCH time on this already. 😟 Had no problems until I installed the upgrade this week-end. Previous version worked just fine! you would think Apple would test this stuff before going live with it.......but then maybe that is what they are using US for!

The library file gets updated when upgrade to a new version of iTunes. Fortuantely iTunes makes a back up of your library before it gets updated. It stores the back ups in the "Previous iTunes Libraries" folder under the iTunes folder in My Music.

If you rename the current iTunes Library.itl file in the iTunes folder and then copy the latest one out of the

"Previous iTunes Libraries" folder into the iTunes folder (naming it iTunes Library.itl), iTunes should be able to load it.

You need to make sure you completely uninstall iTunes 10.4 before trying to install 10.3 though. See http://support.apple.com/kb/HT1923?viewlocale=en_US for how to do that.

http://www.tipb.com/2011/06/17/daily-tip-downgrade-itunes-105-beta-windows-pc/ explains how to downgrade iTunes (it mentions 10.5 beta specifically, but it will work for any version of iTunes).

One can only hope that Apple fixes the sync problem in the next version of iTunes, otherwise the only other "fix" is to do a complete restore of your iPad (and hope the bug doesn't occur again).

And now to make matters worse, I'm trying to install the iPhone 4.3.5 update and it won't work because the backup in iTunes never terminates!!!!

Hey Apple, this is very frustrating!!!!

I just hooked up my ipod touch and was notified that there was a software update. I couldn't get out of that screen fast enough. I believe you have to have itunes 10.4, which unfortunately I do, to get the update. So going with the current Apple flow of reducing functionality, I'm betting that if I update my ipod, I'll lose the music player function. I'm sure Apple will tell me that I can still listen to my music by using iCloud!!!

BRING BACK BACKUP TO DISK!!!!!!!!!!!!!

Yeah I'm having some issues too. I'm still able to connect to the iTunes store though. However, I have my taskbar on the left side of my screen and iTunes seems to think it is on the right side. Using Windows 7 64 bit SP1

This link also helped my situation out. I followed it but did not defeat and everything is working ok. I would recommend those having trouble trying it. It appears that uninstalling in tunes completely is the trick although unfortunate that it has to come to this. At least this link shows the correct way to do so so if anything else is wrong at least you know this step was done properly.
