Thats what the RPT file says, over and over. ===================================================================== == c:\program files\steam\steamapps\common\arma 2 operation arrowhead\ArmA2OA.exe == "c:\program files\steam\steamapps\common\arma 2 operation arrowhead\ArmA2OA.exe" ===================================================================== Exe timestamp: 2012/03/30 19:52:21 Current time: 2012/03/30 21:00:43 Version 1.60.87580 ErrorMessage: Data file too short 'C:\Program Files\Steam\SteamApps\Common\ArmA 2\addons\air.pbo'. Expected 120178246 B, got 91095040 B how do attach the md5 file?

I try to start the game in steam library and it just pops up with an error saying the air.pbo is too short. Tried to fix by running as admin and validating, did not work. Tried to fix by running as admin, did not work. Tried to reinstall the game three separate times, cleaning registry and all that good stuff, does not work. I tried going to the game folder in steam and running the game that way but it does the same thing. I did get the game to go to a splash screen once but then it gets close to the main menu, then quits to the desktop with a message box saying "Bad Serial Number Given in Setup" What to do?
