I've been having this error message since downloading the divinity engine that stated "The files of mod 'Main' and/or its dependencies are invalid. This can be caused by corrupt files or some files may have been changed. You wont be able to play this mod in multiplayer."

I've tried deleting my public folder inside the Divinity game's steam folder, renaming my Divinity Original Sin folder inside .../documents/Larian Studios and made a new profile, and still this problem persists. I even tried deleting the entire game and reinstalling it but still nothing.

Can someone help?
