Hello everyone, i just got the upgrade disc from the sony center. Did everything want the manual wanted me to do,and everythign went fine so far. But after i put in the Vaio Supplement dvd the 2nd time, my computer froze. So i restarted it and tried it again, but now it wont open again. My question now, should i recover my system again to vista and try to upgrade it again OR is the supplement disc not that important. Because the windows 7 runs just fine now. (so far that i can tell) Thanks for your help guys!
