iTunes 8.0 - Genius - unknown error 4010

Same here-- I've tried all the suggestions (quitting, repairing permissions, creating a new user and blank iTunes library, etc.) and nothing has worked.

If only I could figure out how to restart the whole process. It runs through step 1 really fast, and I have a hunch that I might get it to work if it were to re-analyze my library. Adding music or reinstalling iTunes 8 doesn't do it.

Well I don't know how or why but it's working! And quite well too. I just kept canceling and retrying and now it's a go. Good luck all!

Same issue here, with a 3.27GB library. I tried reinstalling it and restarting my mac. Nothing. Looks like a cool feature, I'd love to see how well it works for myself.

It is not working for me either. I am getting this same error 4010 even after and computer restart etc.

I'm having the same 4010 error. I've quit, restarted, and it still doesn't work.

Same error with >100 gig library and I've tried like 50 times with no change. Slightly frustrated now because my iTunes keeps crashiing.

Yeah I've been having the same problems as well. Its unfortunate cuz this seems like an amazing feature. I'm going to try restarting my Mac OSX and see if that does anything. I'll keep you guys posted.

I've been getting a "network connection timed out" error on step three of the Genius process since downloading iTunes 8 yesterday. I have a music library of about 140gb not including movies, TV shows and Podcasts. I get about halfway through the 'Delivering your Genius Results' progress bar when it stops and gives the "network connection timed out" error.

I'm frustrated with this as my work MacBook Pro was able to get through the process in one try, and I was very impressed with the Genius playlists at the office. I want it to work from home though, that's where most of my music is.

So restarting the computer definitely did not help. Everything is updated and alive and well. So it has to be just a server overload issue. Hope this gets fixed fast but knowing Apple I'm sure it will! Thanks for all your guys help as well.

Just for the record it took me four tries with 315gb of library to complete the "genius" up/download and be up and running. I attribute it to server loading, and I had to turn everything else off while doing it to open upload bandwidth. I must say I am impressed with what I see of the lists it makes though. Very interesting and useful for those like me with huge libraries and many dinner parties LOL.

I still see this problem. In step 2 (Waiting for Apple to process) after 15seconds I get the 4010 error.

I tried a whole lot of things:
- repairing permissions
- Removing all plugins
- Only iTunes running on the system
- removing the iTunes Library Extras.itdb and iTunes Library Genius.itdb files, so they could be rebuild
- Going over my account info (updating credit card info)
- Updating broken ID3 tags in my library (had some with UTF8 junk)

And nothing helped.

I'm a Belgian customer, so I connect to the Belgian iTunes store. Maybe there could be a problem there?

I tried it it did not work for me either!

I'm wondering if there aren't two separate problems that have the same symptoms. Some people seem to be able to succeed just by trying a few more times to upload their info.

I've tried at least 50 times over the last day and a half, and have been unsuccessful every time. I have been successful, however, in uploading information from a small subset of my library. So, either there's an issue with the size of my library (42 GB), or there's a corrupt file somewhere in my library that's causing the problem. It seems unlikely at this point that just "trying again" is going to fix it for me.

Well after a ton of trying, I restarted iTunes, and it worked the first shot. Not sure if it was restarting or Apple fixing things - but now it works. (I have an 80 gb music collection).

I am having this issue also
