I was wondering if there was any way to get the Ti-nspire CAS software for free? I used the CAS software for learning how to program certain math concepts (quadratic formula, Pythagorean theorem). I used time-stopper, but I accidentally opened a file, which opened the actual program and made it expire. I used Revo Uninstaller to delete all keys, but when I re-installed the software was still expired. I have also tried downloading a previous version from, but it didn't work either. Should I contact TI? I threw away the box with the serial number, and I don't have the receipt either.

I would purchase the product, but as a high school student, I don't have that type of money. Nod32 fix v1 9 nsane down.
