why does multiplayer prevent me from logging in to gamespy?

The following message is returned, when I try to log in to gamespy!

"You have been disconnected from gamespy. You may have logged on another computer."

I only have one computer! Is it trying tell me, I quit gamespy without loging out? If that is what is telling me, there should be a feature to log out? or when I quit, it should automatically log me out?

dont worry it is the stupid server, it does it all the time.

Its the stupid people not the server. I'm tired of people bashing gamespy but they don't know that their causing it themselves.

HERES WHAT HAPPENS:

FSX was designed with Gamespy and about 5-10 lobbies. Everybody goes into the free flight lobby and pays no attention to other ones. To prevent lag, Gamespy puts a max players on each lobby like any server does (lets say..500 people). They do it to prevent lag. People flood into gamespy and then gamespy disconnects you when there is too many people in that current lobby. ITS NOT GAMESPY, ITS YOU!

so what can we do to prevent this?

Suppose, if max users is logged on, they detect that and send msg 'max users logged on' instead of telling you that somhow you got logged on to another computer when you yourself know that aint true! very confusing?

This is not some homemade basic program. Either Microsoft or Gamespy must bear the blame for this fantastically bad design. I'm fine with the engineers missing their initial assumption, but that they still haven't redesigned the lobby concept is not acceptable.
