mitchell65: thank you. The stick itself is fine. I plugged it into my other computer and it works just fine there. I should have specified, but the computer I'm having trouble with is a laptop. I tried plugging it in all 3 locations, and neither one works.
DeaconFrost: unfortunately, I don't have the expertise to make the updates work properly. They worked up until a certain point last year, and I really have no clue what went wrong.
