Well ive been using Vista since it came out and bought the upgrade version. Origonal I just upgraded from my xp installation but with my new PC I just did the thing where you install vista upgrade then upgrade from that. It was working fine for awhile but today when I turned on my PC its locked and I need to activate it and it wont take my upgrade license key so i figured I was screwed so I tried to reinstall vista and start over but now it wont boot from my vista dvd. When i try to boot from the dvd it just starts up my vista installation.
