Well, it seems I somehow fucked up the main mod

I can't even start a game now or select it as dependency.
That's the reason I can't load your mod I think, as it depends on it.
edit: I did now a file verify and it still won't work

I can select the main mod and activate it but nothing will happen.
and in C:\Users\YourUser\Documents\Larian Studios\Divinity Original Sin\Mods are only mods downloaded by the steam workshop I think, as the cowsimulator is in there.
editagain:
Got it fixed! you just need to remove the Main folder in the mods folder.
