Played HLA for a long time on this pc with no problems. Installed this mod, played it once, and then when quitting the game the screen has gone black.

Now when loading HLA, the menu screen is all black with some fog on the floor... when loading in to the game, the screen is black. I can still shoot/hear noises etc but the game does not display.

I've tried uninstalling the mods, reinstalling HLA, verifying integrity, graphics drivers... literally everything... But no matter what I do the game now is just a black screen even after a fresh install with no workshop items etc

Any ideas how to fix this?
