I am running Parallels Build 6.0.12106 for MacBook Pro (Lion 10.7.3) and have a Windows VISTA VM that used to run just fine. However, now I can't start or stop it any more: all I see is a black (blank) VM-Window and my only option under "virtual machines" is to stop this VM. However, when I try to do this, I get this error message (sorry, it is in German):
Dieser Vorgang kann nicht abgeschlossen werden, da sich die virtuelle Maschine "Microsoft Windows Vista" im Zustand "anhalten" befindet.
I have waited for several days, but nothing ever happens. I quit Parallels and restarted it. I get the window with my VMs to choose from and other VMs work fine (windows XP for instance), but the VISTA VM just goes to the black window and sits there. The VISTA VM has very important data on it, so I can't simply reinstall it, I need to run that hard drive image again!
What can I do?
Thanks for your help
