I just installed ArmA 2 and Operation Arrowhead from the Steam store. When I attempt to launch them, they both come up with errors preventing launch: ArmA 2: "Data file too short 'c:\program files(x86)\steam\steamapps\common\arma 2\addons.pbo'. Expected 853343647 B, got 660602880 B" Operation Arrowhead: "No entry 'bin\config.bin/CfgInGameUI/MPTable.shadow'." and "Data file too short 'c:\program files(x86)\steam\steamapps\common\arma 2\addons.pbo'. Expected 853343647 B, got 660602880 B" If anyone is familiar with how to resolve these issues, help would be greatly appreciated.
