Same problem, start the modding tools from Steam and it takes me to the launcher, cleared out my mods it then tells me "Your Current Tileset is out of date, update from Modules\Native\Get_tileset.bat*" but theres no batch file there. The game then tells me than a huge swathe of Anim files aren't found, would I like to ignore the error also send to Tale Worlds.
*(cant remember exact name)
So far I've sent several reports of the error but I've just closed the tools otherwise. The files were installed yesterday, I'm on the Beta branch for the main game so that may well have an effect?
