Kept getting a message that "Windows as expiring in xx days". I tried entering my product key for Windows, but it would not accept it. Parallels and Windows Vista Business came pre-installed on my MacBook Pro several months ago. Today, I try opening Windows, and I cannot get in. Evidently, I let it "expire". Ok, my dumb fault - but what do I do now? I cannot get into Windows and thus cannot get to the Windows verification screen again. I tried calling the "Windows Verification Number" but evidently, you have to be able to access Windows - no can do. . . Any suggestions?
