The server you are selecting has not updated. Give it a day or two or try out an Official Uber Server.
no i tried about 10 servers and they all gave the error , its on my end somehow . I hope after i reinstall the game it works. still doing it after the uninstall/reinstall
Server version didnt get bumped up on the Steam side. It should be changed shortly, sorry about the delay.
Funny thing is, I did get an update, but I am still getting the message that I am incompatible. This is on official servers as well as others. This is as of 8:38 PM Pacific time.
