I just downloaded them from GOG. I had read that the GOG version worked better than Steams. However I get black screen on both and warhead has black screen with sound but no video plus I have to shut down I can't task manager kill warhead. Crysis just goes black on start, then after a minute or so crashes back to desktop. Tried compatibility mode vista and 7, run as admin, reinstalled june 2010 dx, ran dxweb setup, Did some renaming and moving of crysis exe files. Nothing so far has worked..
