FS2004 Multiplayer Problem

A quick question if any of you have experienced it and have figured out how to fix it:
Via the Zone, after connecting to a session, the game opens up like normal, then it says loading scenery, textures, etc., and then finally comes to rest at a frozen picture/screen (in my case its that of being in a Cessna cockpit looking down a runway).
Is there a solution to this problem? For the most part joining a game isn't the weird part, but after FS2004 has already loaded and a frozen screen comes up. At that point, sometimes I have to reboot.
Any recommendations are welcome! To some of you who may ask, I have the following system performance:
P4 at 2.2ghz, 256mb RAM, XP, 56.6 modem, basic 3d card
So as noted above, the game does work right on my PC, but for some reason not with multiplayer.
Thanks
