ToCA Race Driver 3

Having issues with 2 controllers split screen on TOCA 3
Tried to plug in 2 Xbox controllers into the USB ports. Game wont start unless only one is plugged in. game works if one is plugged in, but if 2 controllers are plugged in, the game hangs in a black screen, until i pull one out. Its not the only game that does this fro me though. race 07 and Flatout 2 does this to.

Anyone know why that might be? I wouldnt mind getting split screen to work for this game when some people come over, for fun.
