Not Able To Access Servers

I recently got the game just a few days before the update, Ive played on a few servers for about a total of 2hr. Since the update i have not been able to start loading servers any more, it will start but immediately stop and give me a message saying the server im trying to play on is an updated version. I have tried uninstalling and reinstalling, EVERYTHING! Nothing is helping, i can only play on legacy servers and single player. PLEASE HELP!!
