No problem, but I want to copy my data to the computer first. Since the touch screen doesn't work, I cannot use the send command. Also, the connectivity kit will not allow transferring files (throws an error).

There is something to try first. Turn your calculator off. Once it is off, hold down the three keys with the alpha C F and O on them. That is the key with the blue "units", the x^y, and the comma key. With those 3 keys held down, click ON. You should now be in the "EA656 DIAGNOSTIC" screen. Press 8 on the keyboard and it should go into the "Touch Panel FW Code Refresh" screen. After about 10-15 seconds, it should say "TP Code is OK". If it says that immediately (<1sec or so), then it may not have worked.

If it took 10-15 secs or so, I suspect the touch panel screen is working again. Reboot by pressing 9 for the "Reset" and you will boot.
