All is in the title : When my game start, after the connection panel, a little youtube's video start, when I close it : I can't click. My game worked on my school's PC, but now, I can't press any button, must alt+f4 to close the game. Thought it was a dual screen problem, but when my second screen is disable, still this problem. Any idea ? :'(
Most likely you met UI crash, First try to update your drivers: Download and install drivers from here: http://support.amd.com/en-us/download/desktop?os=Windows 7 - 64 Post here if this won't be fixed by driver update.
Also I see other problem with your computer configuration. It's not related to crash you met, but it's might cause problems in future: As you see you have 8GB RAM in your PC, but because of 32-bit OS limitations you only able to use 3.5GB, less than half. Game also will be pretty limited in memory usage (2GB) which might result in crashes. I'm recommend you upgrade to 64-bit OS.
