Thread: Serious Connection Issue, Bizzare...

So, I'm going to preface my problem by saying, No I don't use a router, and yes L4D2 is on my list of exceptions through the windows firewall (although the firewall wasn't even ON the first time I had problems).

Basically every time I try to connect to a server or lobby it locks on Establishing Connection until it gives up and makes a new lobby for just me that no one can seem to join. This is the message I get in console when trying to hit quick game:

SignalXWriteOpportunity(3)
BinkOpen( c:\program files\steam\steamapps\common\left 4 dead 2\left4dead2\media\l4d2_background01.bik )
Dropped Louis from server (Server shutting down)
