-I am having problems with Parallels for Mac. It worked fine up until about 4 weeks ago when I downloaded a scheduled update. Since then Parrallels won't open the virtual machine I had been using, and keeps wanting me to create new ones. First time I tried that I got a message saying: -512 MB Physical memory, SCSI controller is not installed, trying to boot from primary master IDER drive, but failed, tried to boot from CD_ROM but failed, No boot device is available. -I tried again with another V Machine, this time it asked me to install my Window XP operating system, which I worked. However, it doesn't recognize the primary VM, and I can't access the info I had on there. I've read through some of the posts by others with this problem, but have been unable to resolve my issue. I do not know where to go to set the IDE order which was recommended by others. Hope you can help. Running Parallels 4.0, build 4.0.3844, installed 5-5-09. Running Mac 0S 10.5.7, Have 512mg physical memory, Parallels Install disc is in CD-ROM Drive. Do not have Boot Camp installed
