Since Monday, not a greatdeal has happened with respect to my computer. Freedom Scientific has not replied to my e-mail. this is disappointing but not surprising, since they made it clear to me that they would only help me over the phone. Unless I get sick, I will have no holidays until July 1, Canada Day. I also have an e-mail in to Serotek to see if they can help me. It's only been just over a day since I sent that in, so we'll see what becomes of it. I don't know if it's this Catalyst Center or something else, but I can't imagine it's a hardware issue. I'd think display driver, but SAToGo apparently has nothing to do with the display driver. But everything else non-screen-reader I've tried seems to work, so I just don't know. This makes no sense. I appreciate the encouragement people have given me on this issue.
