I don't expect it to be inconsistent like that please rule out a bad mod, so: try unapplying all mods in frosty, except for one, safe, newly created mod on nexus. then "launch" in frosty to apply then launch the game with the CMD if it doesnt launch, try launching with the CMD without any mods, it should at least launch i got it to work now thanks one (or more than one) of my mods was probably the cause now i gotta see which mods work and which dont but this game takes years to load lol but thanks
