Every time I launch CMSF NATO and get to the menu game crashes after few seconds. If I manage to start campaign during these few seconds it will run without crashing, but there are problems with ingame text- units and ammo dont have their names. Also, there are no soldier functions written in bottom left corner, instead there is a gray transparent bar. I've already reinstalled CMSF several times and the result was always the same. I'm using win7 and RadeonHD6770M.
