1. Update the dll. files in both Arma 2 and Arma 2 OP in the steam file. Remember the dll. files are located in the expansion folder in OP folder.
2. Important step : Start > Type %Appdata% > Local > Arma 2 OA > Battleye and paste both updated dll. files in that folder. Once you do that all the error's should go away and everything should be work fine. At least for me it did. So go head and give it a try!
Here is what it looks like >
All the updated dll. files can be found here > http://www.battleye.com/download.html
*REMEMBER THIS WILL ONLY FIX COMMON ERRORS*
