I cant ever seem to join anyones SCCT games & no one can join mine, the name flicks up, the disapears quick, and then when I join someone elses, it keeps saying "Cant join", or stays on the join screen for ages, then comes up with all sorts of other random stuff like "already in this group" or something?
Whats up with that and how do I fix it?
I'm on patch 1.5 also

Also, I dont know how to open the ports?

I have the same problem
