iBook G4 Mac OS 10.4.11 iTunes Version ??? (Can't get info - won't open) I'm pretty sure I was at version 8 around the time I tried to uninstall. I followed instructions here: http://support.apple.com/kb/HT1224 I followed all the steps and everything was fine until I tried to empty the trash. All items emptied out except the iTunes application itself. I get an error message that says: "The operation cannot be completed because 'pgs' is in use." What the heck is 'pgs'? I found pgs folders in the System Folder/Mac Help. I'd love to trash them, but don't know that I should. Any ideas?
