Men of War 1.17.5 crashes

[Gorn085]

Hello,
i have a problem with Men of War(Steam Version) in the Version 1.17.5
My game crashes every 5-30 minutes. I am playing only mp and this is annoying. I get this errormessage. I tried to reinstall the game but it still crashes. My Systems runs Windows 7 x64 so this could be a reason but is there a solution? I am running men of war in admin mode and tried all compatibiliy modes (XP SP3, Vista,etc.) but no effect.
