hey dude i registered specifically to help you out
i had this problem too and it turned out to be that i was using dual monitors. please tell me your using 2 monitors?!
the solution is simple, disable the monitor thats not your main desktop and start the game, it should start up normal
you only have to do this once. you can enable your monitor again at any time and then when you try and start the game up again, there should be no problem (even with your second monitor enabled)
