before 1.64 game was running right, but today i got the patch on steam downloaded it and then later got a small patch of 9 mb wich was a fix apparently. now i get a crash every time i start the game giving me error (uploaded zip) i tried with and without mods ( the ones my group uses), same crash so the mods are not the cause it seems. did an steam game cache check and all its right so what can i do?, reinstall? :( thanks
