I'm a total novice with computers and everything and i got a burnt cd of photoshop 7.0 . There are all these other files and folders but i can't find the setup file. WHen i open the adobe photoshop thing that is 15 mg, a dialogue box pops up and says "could not complete request because of missing or invalid personalization information" i have no idea what's wrong. Does this mean that the cd i burnt is useless..? PLEASE HELP
