hello guys, im having a problem with titan quest... the problem is when i double click on titan quest.exe the screen remains black (that's all u can see) the computer doesnt answer, and i have to restart my system.
I have an AMD 3200+, 1gb ram, gforce 6600 256mb, 250 gb disk space... i think that my pc perfectly suits the game requirements, but...why is this happening? i've tried many things..but it's the same after trying once and again...
please i need a hand, thanks for your time...
