My game crashes too, only it crashes about 10 minutes into any game that I start. There's also a black square that glitches around my mouse cursor when I move the mouse. The game runs alright for a few minutes once I start, but about 5 minutes in the screen flashes black briefly, and then ten minutes in I hear a noise like a desktop error and my game crashes and a window says "Sins of a Solar Empire:Diplomacy has stopped working." Does anyone know what's going on? It's not a graph
