Album recognized by Gracenote on one user account, but not another

Question

When I am logged in to my computer as Administrator, iTunes recognizes my CDs via Gracenote with no problem. When I am logged in as "All Users," however, Gracenote is unable to retrieve albums and track names.
iTunes under both user accounts is 8.0.2.20, but when I'm logged in as Admin, a silver window pops up labeled "Processing..." and the tracks import normally with their names, artist, etc. When I'm logged in as All, however, a different window pops up when a CD is inserted; it's blue and reads "Querying Gracenote..." but it can never retrieve album information and times out.
Not sure whether this is an iTunes settings problem or a permissions/security issue that's causing this problem. I've made sure "Automatically retrieve track names from the internet" is checked in Preferences, and I've tried choosing "Get CD Track Names" from the "Advanced" menu, with no luck.
If it matters, I do know that iTunes has been installed, uninstalled and re-installed at least once on this machine, and that some old and new libraries have been moved around between the two user accounts. Any ideas?

In your wife's account:
Try trash the com.apple.iPhoto.plist file from the HD/Users/ Your Name / library / preferences folder. (Remember you'll need to reset your User options afterwards. These include minor settings like the window colour and so on. Note: If you've moved your library you'll need to point iPhoto at it again.)
*What's the plist file?*
For new users: Every application on your Mac has an accompanying plist file. It records certain User choices. For instance, in your favourite Word Processor it remembers your choice of Default Font, on your Web Browser is remembers things like your choice of Home Page. It even recalls what windows you had open last if your app allows you to pick up from where you left off last. The iPhoto plist file remembers things like the location of the Library, your choice of background colour, whether you are running a Referenced or Managed Library, what preferences you have for autosplitting events and so on. Trashing the plist file forces the app to generate a new one on the next launch, and this restores things to the Factory Defaults. Hence, if you've changed any of these things you'll need to reset them. If you haven't, then no bother. Trashing the plist file is Mac troubleshooting 101.
