running mac OSX v 10.4.11 parallels desktop 2.5 build 3214.0 i opened parallels today and everythings working fine. i leave full screen to transfer a file and notive parallels is telling me to update. sure. i DL, run update. it reinstalls parallels....ok?....when i try to open, telling me i need to install guest OS? i already had windows SP2 installed and working fine...not to mention A BUNCH LOAD OF IMPORTANT FILES AND PROGRAMS ON IT....now nothing. my question is how can i make the updated parallels desktop run the same windows it did before i updated?
