Game disconnected: Client closed down connection make sure...port 3659 is open.

So sick and fed up of this error now, I can't even go 1-2 games without it happening. Really disappointed nothings been done to solve this, as it's more than just a handful of players that are getting it if you read around the net. If I could have a dollar everytime someone says to forward certain ports...

It's actually frustrated me so much this evening, I uninstalled my game and don't plan on coming back till theirs a fix.
