After an election which I won, I clicked the button to continue the game. The game froze and then crash, giving me a Direct3D error. When attempting to initialize the game again, it would refuse start Direct3D, giving me different errors each time. Restarting my computer solved the problem, but needless to say this is a bit extreme to have to restart my computer to get the game to work again.
DirectX 9.0C is installed, I am running XP SP2 with an Nvidia Geforce 7600 GS video card.
