Aliens vs. Predator (2010)
WARNING DONT TOUCH BRIGHTNESS EVIL!!!
I had the same two problems!
1. DirectX9 did not start.
2. Brightness was to dark.
You can fix both problems!
Go into your steam games, right click on avp->properties->local files tab->verify integrity of game cache.
It will check the files and update them if something is wrong/currupted.
Reboot your PC and start the game with DirectX9.
Then it should work
