I've been playing Arma 3 for quite a while now however since about an hour ago it keeps deciding to crash when I try to play multiplayer. For example the first crash happened in game when I accessed a customisation screen for a gun. The second time was when I was 'receiving data' while connecting to a server and the final time was after I had finished 'receiving data' and had also selected a class it crashed.

I use Six Launcher
