Unable to connect to host

Hey guys,

I got in some hacked lobby and since then i get every time i connect to a game: unable to connect to host.
How can i fix this?

Thanks,

I had the same problema last night. Even though I used deadfingers tutorial to lower the ping to 100, but last night had that problema so I raised the max ping to 200 and it connected without any problem, but I really think it was a general server issue caused by an on line update.
