Has anyone been able to activate Parallels Desktop for Mac version 3 with a trial key? I'm a registered user and requested a trial key to evaluate the new build. Parallels sent me one, but it doesn't work. I get this message: The activation key cannot be used with the current version of the Parallels Desktop! Gee, thanks. I requested a new trial key, but to no avail. I'm downloading beta 4 of VMWare Fusion right now. If Parallels doesn't get their support act together, I'll probably switch.
