Possible solutions for frozen Ti-89 Titanium calculator with Address Error

[Roses]

So, here's the situation. I recently got a Ti-89 Titanium, and i was trying to put some games on it. I had it plugged into my computer, and i sent Phoenix, Tetris, and Falldown over to it. Going through Var-Link and selecting the program didnt seem to work, so i decided to try downloading an OS. the OS i downloaded was DoorsOS. I sent the OS over to the calculator, and it still didnt work. After a couple tries, i got "DoorsOS" to appear on the line, and i hit enter. This froze up my calculator, leaving a busy icon in the lower right, and an "Address Error" at the top. Removing batteries and putting them back in doesn't seem to work. What can i do?

Additional Information: pressing second and the green key seems to work, but i can't get any other buttons to register. Removing batteries is the only way to shut it down, and when i put it back in again it just continues the freeze error.

I'm new here but it you know you should never put games on your TI's. Sometimes the games can backfire and lock up your calculator. I would try taking out the batteries for a day and then putting them back in. If that doesn't work I really don't know what to tell you.

if you take out the batteries, there's another battery in there for the memory, under a screw panel i think. one of those circular 1.5v ones.
