Doesn't mean anything that your config is OS
is it windows or linux?
do you have a recent version of the software, and is your gpu/apu old?
along with the normal Ratfighter_NMC.exe executable, there is another one called Ratfighter_NMC.console.exe
if you run it, the game's log will appear in a console window while the game runs. I need to see this log to know if an error occured. (to get the entire log, follow the normal steps in the game window until you're locked)
