This is very strange. Parallels 5 for Mac with Windows 7 VM has been running fine for two accounts on the iMac. However, now one user can start the W7 VM but the other can't. For the user it doesn't work there's a message saying: The virtual machine is corrupted. The virtual machine cannot be used because its files are corrupted. But they aren't. The windows7.pvm runs in /Users/Shared/Parallels and has done since day 1. The version in use is Build 5.0.9376. Any ideas? I've spent 3 hours searching for clues but all solutions so far haven't been relevant
