Well, the next step that a lot of people are suggesting I take is to turn off UAC in Vista. Since I'll be doing that anyway, I might as well try it. I seriously doubt that will solve my problem, but stranger things have happened. All I want is for this to work. First I went and bought a non-expandable machine, and now this. I don't want to have to send it back toDell. I hope I'm totally wrong and turning off UAC actually solves this problem.
