Tried verifying the files, tried deleting the appcache folder of the Steam app like the support pages suggested, tried restarting Steam, restarting the PC, turning off my firewall... nothing has worked. All I get is a window claiming the game is being launched which disappears in an instant and then nothing. Trying to launch it several times in a row gives me an error message saying the app is already open, which the task manager disagrees with.
Other games will launch fine. Is anyone else having trouble with this particular game on Steam? I'm new to PC gaming, still don't really know what I'm doing here. Thanks very much!
