Good day everyone. I recently installed Ballistics the racing game on my Linux Operating System. Everything was running perfectly until I hit the restart button, and then my game froze. Since I knew there was a problem, i got rid of the game, then I tryed to reinstall it, but now it won't work. So, I am thinking it has something to do with Ballistics' copy files that are saved all threw out the computer. My question is, where do I find all of Ballistics' copy files, so that I can remove them?
