Did you try these steps?

In addition to not being able to synch my iPod Classic to my Windows XP PC ever since version 7 came out -- this morning, I opened iTYunes, and it started loading multipl versions (over 30) of AppleMobileDeviceService/Helper.exe, up to the point where over a gigabyet of memory was in use (my machine has never been that high, it was cutting into virtual memory and wirting other memory temoporarily to my hard drive). This went on for almost an hour, and never subsided, until I closed iTunes. Apple better fix this soon -- they're not gonna win any quality awards putting out trach upgrades like this.

I have the same problem. When I run itunes, many instances of applemobiledevicehelper.exe run in my task manager taking a lot of memory. I have to manually delete them. Is there a way to fix this ?

If you don't have an iTouch or iPhone, your iPod doesn't need that AMD program so you can delete it

Yeah, the same thing happened to me.
Ever since i updated my iTunes, my computer has been totally messed up.
Anytime I open up my Itunes, my computer goes crazy and the Virtual Memory becomes low.
And then, if I try to shut down my computer, it states that there is an erroe, involving the Apple Mobile Device program.
So, about two weeks ago, I deleted it, thinking it wasn't necessary.
But when I deleted it, my computer and iTunes would not recognize my iPod Classic.
So I had to restore my computer so I could retrieve the Apple Mobile Device support.
And now, my compuer is going crazy again, and I get scared opening iTunes.
What should I do?
Someone please help
=(
Thanks

I've been having ths same problem. Follow the instructions on apple.com to uninstall ITunes and Apple Mobile Device. I just did it today & so far it seems to be working. It's been about 5 minutes since I reinstalled Itunes 7.7 on Windows Vista and I have not had the error message.

I have an IPOD nano & it is now syncing with ITunes.

If you just uninstall Itunes and not the AMD you will continue to get the messages. That's what I think I did wrong initially (I've been going through this all week).

FYI, you will not lose your library of music etc. Once you reinstall Itunes everything comes back. I did not have to save my library prior to the uninstall.

Good luck.

PS. uninstall ITunes - restarted the computer then follow the steps to uninstall AMD.

I hope it works for you for I know what you've been going through.
