I upgraded from Parallels 4 to 5 just fine. But when I did the 9376 update, Windows can no longer boot. I hits a BSOD with a REGISTRY_ERROR and then immediately restarts and goes to the safe mode screen. I've tried all the options on that screen, but none of them work. I've rebooted the iMac and that didn't change anything, either. This is the STOP: oxoooooo51 (ox00000003, ox00000001, 0x00004000, oxe1946040) Any solutions?
