Haha, no worries Pmosis. I hate it when people say "Don't worry, fixed the issue", without actually posting how they solved it.

Experiencing same problem. Have also uploaded my .RPT files (Arma 3 Crash Log).

Hello,

bidmp and mdmp files were not being created no matter how long I waited.

However I took a look at Windows Event Viewer which told me that Battleye seemed to be at fault:
(Faulting module path: C:\Users\NAME\AppData\Local\Arma 3\BattlEye\BEClient.dll)

Downloading the client .dll from battleye website and replacing the one I had, seemed to fix the issue. Perhaps the one I had was corrupt possibly. Anyway Thanks for the help.
