My specs: Windows 7 64bit AMD FX 8150 8-core 3600MHz CPU 16 GB ram GTX 660 Ti All drivers/windows updates no more than 1 month old from time of this post. Steelseries rival mouse with associated engine/driver software installed. Yesterday was the first time I've been unable to launch the game. I've deleted USER folder, deleted manually and then reinstalled everything, disabled my antivirus, verified my files like 15 times, and I cannot get the game to launch. When I hit the launch button, the Crashhandler.exe console window pops up, with nothing on it, and then I tell the prompt to send my crash report with the 4 buttons that pop up, and then I close the console window and I'm back at the patcher. So....any ideas? I'm also a subscriber, so it is annoying that I cannot rent things to try out at the moment. The only thing that APPEARS to work is the patcher, which is updated. EDIT: I solved the problem. It turns out my driver for my secondary monitor, which is not an Nvidia or AMD driver, has been messing with my computer. Do NOT use drivers from non-reputable companies! Uninstalled the driver (from China), and now everything works just fine.
