A Land Far Away

Hi.
I am trying to connect to the servers to play, but I am getting a message that I am missing a required expansion pack. I've installed SOZ and the haks. Is there anything else that I am missing?

Thanks, in advance, for your help.

Do you have Mask of the Betrayer installed as well?

Thanks, Mick. That was it. Once I downloaded and installed MOTB (plus repatch), I was able to get in.
