hi, if some of you dont mind to start over your mission progress and other stuff, but want to just make it work again, since last resort is telling you that the swat.cfg file is damaged however missing, what I did to resolve this is:
> delete the swat.cfg file
(its possible that there maybe 2 files of .cfg but I recommend deleting both the 2 of them)
and thats pretty much it, run last resort again and it should run normal though youll have to set your preferred settings/keybinds again.
Go for this option only if you dont really mind to start over again (I wouldnt mind really since I really love this game) or if theres no more choice for you but to just go for this option.
i hope this helps some of you ^^
