we have done install it, i opened co-op, Invited my 2 friends, one of them was able to join very quick, and the other one, until now, cannot join. we checked every single forum for the solution, we have no idea.
we checked firewall stuff, we checked i think everything.
why this is happening ? i saw too many people having this issue… we paid money for the game…
what can be the solution? i just wanna play with my other friend too and its never work.
