I have actually seen something similar to this problem and seen it solved. The way it was solved requires the ti-link cable that connects to the computer. Once the cable is installed by the computer (it comes with a disc), you can go to www.ti.com/calc and find a new OS, Operating System, for it that should fix the problem.
Otherwise, you will need to by another calculator of the same model or one of the ti-30's would be fine for that test.
