My 2nd Gen iPod Touch won't show up in iTunes but does appear in My Computer

When I connect my 2nd Generation iPod touch to my laptop it will not appear in iTunes. It does, however, appear in my Computer.

I have worked through all of the troubleshooting guides on the Apple Support section, and have uninstalled and reinstalled iTunes twice.

This message appears every time I plug my iPod in, and frequently whilst it is still plugged in charging:

'MobileMe Service has stopped working.' This is a pop-up window produced by Windows, I know this is the 'service' that picks up an iPod's prescence but stopping and restarting the service does nothing. My iPod still won't show up.

Please help, I am willing to faff around a bit. Might it be a problem with Windows itself? If so, how would I go about fixing it?

Thanks in advance,

🙂

P.S I have the latest version of iTunes, and the operating system of my iPod is 4.2.1.

My version of Windows Vista is 32-bit.
