If you're manually installing files something tells me the install didn't go so smoothly. Have you tried reinstalling the game? if you don't really want to spend the time redownloading try right clicking on the game in the steam library > properties > Local Files tab > Verify integrity of game cache.
Another thing you can try is overriding the launch resolution as i've had a similar problem with splintercell conviction. right click the game in steam library > Properties > Set launch options and copy and paste this (including the "-")
-w 1024 -h 768
That will launch the game 1024 pixels wide by 768 pixels high. 1024x768 is the resolution standard for pretty much every game unless its indie developed and constraints aren't taken place.
I hope this helps but if it doesn't all I can say is try a reinstall if you can be bothered with it :P
p.s what were the files that steam recommended you to manually install? because if we can find out what they are we can probably find out whats causing the problem
