I recently purchased a new MBP and transferred the contents of my old MBP. Most all of the new applications have opened without a problem, but Parallels gives me an error message that it "quit unexpectedly" when it actually never launched! I upgraded to Parallels v.4 in Nov '08 and have that activation #, but do I need to reinstall v. 3.0 and then upgrade again? When I look at Parallels under my applications folder, it is indicating that it occupies 24.1 MB on my disk, so it must still be there. Any suggestions?
