I'm writing on behalf of my grandson. He has a very efficient up to date pc using Windows 7 which can play any game on the market. He has been playing Rage for some weeks with a few problems but yesterday 10th February 2012 Steam prompted an upgrade. Once this was done he couldn't even run (launch) the game at all. Please could you help. Many thanks.
Try this, open steam, right click of rage 'the one on the side" , go to properties under tab Local Files, run "verify intergrity of game cache" also run defrag cache. See if those fix the problem.
