I've been playing coopordie for 8 months now. The other day I tryied to play a game with Gouveia but failed. Now I'm trying to join into prof1t's game and can't! His ip shows in the adressbook, but I just can't join

My server wouldn't work as I'm on wireless. Still, it's weird I couldn't connect to yours.

Maybe hamachi would work for this?

Interesting suggestion, I will try Hamachi someday. But how I understand it, you need to chat with other players and give them the name and password or your private network for allowing them to join.

There's a big hamachi network that I host that is made mainly for cooping together or playing on a mod that is not hosted anywhere.
