WestCoast ATC Multiplayer Problem

Hi:I have just recently been encountering problems logging into on-line flying through the FS9 Multiplayer windows. Specifically, I am trying to return to a server that I have successfully logged onto many times in the recent past(WestCoast ATC). Recently, I have been getting a "Log-On Failed" message that says "Not all players were able to join..." or something to that effect. Coincidentally or not, this began shortly after I renewed my interest in flying online at VATSIM and installed Squawbox 3. Anyone have any ideas? Could this, is this, a known problem or conflict with Squawbox? Ports are default. Any help is appreciated. I'll post this in the Squawkbox and on the WestCoast site as well.Thanks In Advance,http://www.my-buddy-icon.com/Icons/objects/red_3d_plane.gifAlex ChristoffN562ZBaltimore, MD
