Game Crashes (without warning or error message)

I also have this, Game plays fine otherwise and finally allows me to use High shadows (I too get a long wait before the loading screen does anything initially), but at random times the game just instantly closes down... no error message or crash message - just back to desktop/EA App. I thought it may have been some CC/Mods but have tried with and without this and it seems I'm not the only one... Hope this can get fixed! :)
