im trying to play orcs must die! 2 with a friend and i used to play it on my laptop which ran windows 7. My new desktop however runs on windows 8.1 and on the minimum requirements for the game it only says windows xp, vista, or 7. When i downloaded the game in steam and tried running it nothing would happen. I would click it again but it says fails to run because its an instance of it is already running. I go into task manager and see that its running but nothing is happening. I have verified the game over and over and it always says 1 file is missing.
