the grims option was dropped many many versions ago.
the latest trainer should work on the latest release of the game, but the grims option was removed a long time ago... like 3 versions of the trainer ago.
Trainer tested working with PRIVATE server with AI bots
Select PRIVATE, then quickly Press F2 then F3 to start the map.
best,

OK. When I read this message I went back into the game to test it, and it works.
I haven't done anything different, so I have no idea why it wasn't working yesterday (but it definitely was not).
Anyway, thanks for looking into it regardless, and I'm sorry it seems to have wasted your time.
