Hi, I was, earlier today, deleting some unused flash applications from my Ti-89 Titanium that were wasting space. Namely the localization things like Cabri Deutsch and Francais and stuff. After setting it to delete a few files, my Ti-explorer on my computer stopped responding, and and so did the calculator. I thought it was just taking a while to perform the action so I left for a piano lesson, but after a three hours, nothing had changed. My computer still wouldn't respond and neither would my calculator. After that I pulled the USB plug out, and the calculator just went dead. Yea, I realize maybe that was a stupid move; however, I tried breaking and resetting the calculator and nothing worked; I couldn't shut down the computer either. I had a backup on my computer of the files I deleted in case they would cause problems once deleted, but I can't restore them because I can't turn the calculator on now, and thus can't connect it to my computer... I would appreciate if someone can help me with this.
