This is happening all the time for my Hany. I manage a couple of races ok. Then i tried to press escape to return to the pits, and the screen froze. I rebooted, and as soon a i click on 'drive', the game freezes again. I have to use ctl/alt/del to get to the task manager. I've tested the integrity of the files in steam, an it reports that all is fine. :-(
