iTunes keeps quitting

[Convert]

Most of the time when I try to play a song on the iTunes store it quits. I'm using the latest OS, iTunes 7, and the only thing I've done recently is updated Quicktime, and now it keeps quitting.

I've deleted plist files... what else do I do?

Thanks

From MacFixIt, may help;

Persistent crashes: Delete .plist files, turn off plug-ins If you are experiencing repeated crashes from iTunes 7.0 -- especially when simply switching tracks -- there are two workarounds that could prove useful.

First, delete the following files:

com.apple.iTunesHelper.plist
com.apple.iTunes.plist
com.apple.iTunes.eq.plist
from ~/Library/Preferences, then quit and re-launch iTunes. Note that after deleting these files you will need to re-establish some iTunes preferences.

Failing the above, look in the following directory:

~/Library/iTunes/iTunes Plug-ins
and remove any third-party plug-ins (including visualizers) you have previously added, then quit and re-launch iTunes.

Hold option at launch to select different libraries/create new ones iTunes 7.0 has limited support for multiple libraries. You can choose a different library for the application by holding down the option key while it is launching. You can also create a new library at the time of launch via this method.
