AoC Has encountered an error and needs to close
Was roaming around the forums and found out my problem came from this Win 7 x64 platform update (KB2670838). Uninstalled it and went from crashing 1-2 times an hour to 0 in 3hrs. After researching it found out the June 2010 DirectX SDK are incompatible with this platform update:
D3D10SDKLayers.dll
D3D11SDKLayers.dll
D3D10ref.dll
D2D1debug.dll
There's a fix for windows 8 if you have this update but can't find one for Win7 unless it uses the Win8 update but that can be found here

hope it helps
