I did everything according to steps, disabled the UAC for Win 7, while making a fresh installation on Medieval 2 Total War, with Kingdoms patched to 1.5. I put in the file - descr_character and campaign_script Yet every time i try to start campaign (after selecting faction when the movie should start) or when starting battle, the game instantly crashes displaying - "Medieval 2: Total War encountered an unspecified error and will now exit." I checked the installation and everything is in there, no virtual files or anything else. Also i tried running a compatibility mode for Win Xp, making another installation, and even putting in empty folders for fixing some kind of menu crash (the ones from second post of the links for Grand Campaign Mod).

Anyone got any advice on how to do this?
