Hello everyone, I recently got Splinter Cell Double Agent (old xbox version) & I got my friend
to get it too. & we're having some trouble Joining/Creating co-op matches online (Xbox 360)

I created a co-op match yesterday & I invited my friend but he couldn't join my session
& every time he tries to join my match this message pops up "The session is no longer available"

He also tried the search function but he couldn't find me. & then he tried hosting... same problem!

Any Ideas ? because we didn't have any problems with Chaos Theory!
