Guys a simple way to start playing again is to goto the Red Orchestra 2 Steam Community page and join the chat. Find a player in there that is currently playing and join his server. This will auto-connect you to the server and if you wanna go back and play again, it will show up (at least for me it did) under recently played tab. I did this several times so I could get a couple of different servers to choose from until TWI gets this server browser glitch fixed.
Hope this helps :IS2:
