I purchased Dirt Rally yesterday. I was able to start it, with the usual issues that I've read about, no ffb (OSW Wheel), no VR, etc but once I setup the controls I was able to play a single stage. Now, every time I try to start up, it show the title screen, but I have no mouse cursor or keyboard response. It simply cycles between the demo movie and the title screen continuously. I cannot start anything. The keyboard and mouse both work fine, as I can press the windows key and get back to desktop with no problems.
I un-installed/re-installed it, same problem. Using the Steam version.
