User blog comment:PreyOnYou/Major Glitches in DLC PS3?/@comment-2138887-20100624171041

I don't know. We (my bro, my friend in CA and me) got in once the night it came out, and it was fine...but after many tries. We keep getting (my friend in CA and me in Portland, OR) when one of us tries to accept the other's game invite is a message that says "ERROR Cannot connect. Please check your connections and try again." Which makes no sense since we're both obviously connected to the servers. We finally got past that on Tuesday, but no such luck last night and we tried for about an hour and a half. We couldn't do either co-op or plain old multiplayer in free roam.
