I keep getting kicked back to the main menu when i want to join a friend

[ZeroWnD]

I have had mods installed for some extra weapons. When i wanted to join my friend it says that we need to have the same mods installed so i decided to just delete and unsubscribe to them, after rebooting the game i keep getting the same message over and over again when i want to join him. We are not running any mods at this point, he isn't either. I have already verified my files and everything is what i should have. But i keeps kicking me back to the main menu with the same "you need the same mods" message.

Does anyone have an idea on how to fix this?

Options, scroll down and find the serverside checksum option. Disable it. Or rather have your friend disable it if they are hosting.

Found the fix already, even after the unsubscribe and deleting mods. There is a folder being leftover in de installationfolder. Delete that folder (since its empty with no mods anyway because you deleted them) and it opens just fine.
