After changing the game resolution my game crashed, since then every time I load the game I get a black screen for a couple of seconds and then it goes back to my desktop and won’t load.
I have removed the game and reinstalled it once and this has not helped.
try going to C:\Program Files (x86)\Steam\steamapps\sourcemods\BMS\cfg
and deleting config.cfg, then try playing.
