GTA IV PC multiplayer issues

[Nuclear Fusion]

Basically, whenever I try to enter a multiplayer game, it loads for a while, and then says 'Disconnected from game session'. This happens with every multiplayer game I go on. It used to work, but now for some reason it doesn't work at all. Any advise on how to resolve this would be much appreciated.

EDIT: Well it seems to be working now, I guess I'll put it down to Rockstar's bad servers and the fact it is a fairly poorly coded console port. Sigh, it's about time we get some more games made for the PC that run fine without issues.
