But at the very least Hyperterminal should work.

If you can do full player upgrades but Hypterterminal does not work, I don't see how that can be? I would think it would be the other way around.

Now there is a known problem on some computers with the "download.c" code (which I did not write by the way) where it doesn't work on some systems. Someone else had a version of download.c that was slower because it printed debugging information to the screen, and that slowed it down enough to work on their system. Unfortunately, I am waiting for someone who's having that problem to mess with different timings in download.c, and find out exactly where the delay needs to be inserted, before I make any changes to my copy in the logo editor. I can't reproduce the bug so I can't experiment with it myself.
