This has me furious now...I decided that rebooting everytime I wanted to use W7 was a giant pain. So I bought Parallels, installed Windows 7 via the upgrade method (since you can't upgrade XP in Parallels, I had to install W7 twice, upgrading the 2nd time.) Now, it won't let me activate my copy of Windows, probably because I activated it on bootcamp yesterday before erasing that partition today. Any suggestions? I'd prefer to go about this the correct way, rather than registry hacks, etc.
