try some things out...update to PRO-C fix3, if that doesnt work then try to dmz your connection...make sure you have the most recent release of the Online Client (.10 r58) as well...you can also press the home button to see if those "13 people" are in the chat or even online...the only thing else i can think of is that you are simply not playing the right game, but it sounds like youre smart enough to not make that mistake so im just not sure...try those ideas and get back to me.
