Whenever I click ''Play'' on Steam I get a window with the message ''Preparing to launch game'' and then it closes. The game doesn't open and I get no error warnings.
I've done everything in the Troubleshooting Tips thread on the Steam discussion forums (Reinstalling, verifying game cache, running in compatibility mode, updating drivers and nothing has changed).
I've already got Dawn of War Retribution, and have been playing that for ages now without any similar problems. The demo version of DOW2 also worked without any problems, although that was about a year ago now.
I can't find a warnings file in the DOW directory.
Does anybody know of a way around this?
