Amnesia only worked twice and would freeze upon exit

[anontux]

I'm using mint 8 32 bit with an ati card. I have propriety drivers installed. I installed amnesia into my home folder home/user/amnesia. The game would start if I went menu/games and clicked Amnesia but would always freeze when I tried to save and exit, the screen would go totally black and I would manually have to turn my computer off. After a couple restarts nothing would happen when I clicked the icon.
It would successfully start if I ran the Launcher.bin file in terminal. Then the same thing would happen. Freeze on exit and now it won't even start using terminal. When I try to run ./Launcher.bin it just gives me info about my graphics card. I tried installing the game in a different folder and it still wont start. Please bare with me. I'm fairly new to Linux. Also, I installed the update and there is nothing at all in the log file. Any ideas?
