The data.win file is larger than nuclear throne, Any other ideas?
Also, should the game be in beta/mods mode or the current mode?
Current mode, although "beta" branch should still work. You can also try renaming the game directory to let Steam redownload it and then reinstalling NTT.
Im a bit dumb and dont know what a game directory is, what is it?
arent i so smart
edit: nevermind, its working, Thanks!
