when i start Parallels I get the VM Config menu, saying the OS is "stopped." It won't allow me to restart. The only button on the menu that responds is start (the green triangle), which brings me to the OS installation assistant. If I hit express, a dark curtain falls over the screen saying I need to restart the computer (in three different languages, which is three more than I need, when a dark grey curtain falls over the screen and nothing responds, neither keyboard or mouse, of course I'll manually restart the computer, what choice do I have??!!). If I do custom installation and then more options and click on ISO image, as was suggested elsewhere, I get asked to pick an application, but there are none to pick -- everything is grey and unclickable. We were running XP on Parallels, and it was working fantastically, and then one day the name of the computer in finder, on the mac side, was accidentally changed. It's now back to the original/correct username, but since that happened I've been unable to run parallels. Suggestions?
