For those of us who bought the upgrade online but have been unsuccessful installing it - what is our recourse? I was thinking to simply wait and hopefully in time as the bugs are worked out try to install it again later. What else can be done? Parallels won't install XP no matter what I do. Only one time I had it installed but due to the many restarts during the install, Windows kept crashing while in use. Any ideas? Does one look for money back or hold tight and hope the problems will be rectified? thanks.
