So I'll just get right to the point. I have been playing DayZ for a while now, and ArmA 2 for even longer, but suddenly something happend. I was not able to launch the game. I used Steam, without Steam. Every single launch method, but nothing work. I used Steam and selected the option "Verify Integrity of Game Cache". First it said that it had found two files which had to be installed again. It downloaded/installed them, but it didn't work now either. After I had failed some times I decided to reinstall ArmA 2. I did so, but it will still not launch. It goes to the little bar with the check-boxes. It checks all of them except the last two and it crashes. Here is the Program Details of the error message: Problem signature: Problem Event Name: APPCRASH Application Name: ArmA2OA.exe Application Version: 1.62.95.417 Application Timestamp: 500d59cb Fault Module Name: StackHash_cc8f Fault Module Version: 6.1.7601.17725 Fault Module Timestamp: 4ec49b8f Exception Code: c0000374 Exception Offset: 000ce6c3 OS Version: 6.1.7601.2.1.0.768.3 Locale ID: 1044 Additional Information 1: cc8f Additional Information 2: cc8f758f4d0878d55a6a170bb68d98b7 Additional Information 3: 5f7b Additional Information 4: 5f7b347fc2f5e6b888b8c3442040edaf I have no clue of what to do. I need help! :L
