When attempting to play Network game in Yuri's Revenge via Origin, using Tunngle. Me and my two friends are having a problem.
When either of them host a game, the other of them can't join it saying: "There is already a player with that serial # in that game"-ish.
We all have the game on Origin, with different product numbers. However I bought a physical copy, while they bought it through Origin.
Do anyone have any idea why it does this? And are there any solution available?
