Basically, when I try to start up the game, it just continues to load - I reinstalled everything that I already had (repaired even), even tried to reinstall the mod a couple of times, and did a few integrity checks with Steam. Unfortunately the diagnostic tool is not available, and the issue arose with version 0.91.

So more or less, game enters endless loading loop, and I have to use task manager to end it. And yes, the first mission is complete, I also tried to remove everything that have anything to do with the simple trainer, so no keybinds should conflict. :)

Cheers for reading!

Did you save when on-duty? Try moving savegames out so you'll start a new game.

Already tried to remove the save-games removed the mod, and started a new game, then re-enabled the mod.

Alas, no luck.

I take it you completed the first mission?
