I ran Battery Check and put it in windowed mode. But when I closed Battery Check, my JJ2 video settings were messed up. So I ran Battery Check to see if I could fix the problem. I made Battery Check fullscreen and exited. Then when I ran JJ2 I got a Fatal Application Error. Now every time I run JJ2 I get this error.

So I tried uninstalling Battery Check but the problems persisted. I reinstalled Battery Check, and yet I still had the problem. Could uninstalling and reinstalling JJ2 fix this problem?

If you could help me with this problem that would be great.

Try running the Jazz uninstall aid from Haze's site. It removes the Jazz registry settings.
