Plutonium

i am trying to port forward on my bell 2wire router. i followed the steps to play custom games with friends and my upnp was still disabled im wondering if i can enable it but im very confused

Ultimateman how do i play coop because when my friend tries to join he first of all has the mod and all but when he joins it says joining game session then he cant join. btw hes joining through the plutonium overlay and also downloaded the same coop pack i did

well now its just bugging out idk tf is happening

I accidentally didnt select Games folder when downloading the stuff and now i cant transfer the stuff in there and it says folder in use when nothing is in use.
