Invite Players button greyed out

Trying to set up P2P with the new Mage Knight module. I go into Server - Host mode successfully but the “Invite Players” button is greyed out. I can’t find anything in the help files or forums on this.

There are a couple of problems with P2P on 3.2.2 at the moment, I am just looking into them. I will work on it as soon as I am able and have Bug 10016 - P2P Client/Server modes do not work in 3.2.2 for it. I think the main problem is that the Invite Players button is dissappearing once you start the server mode up.
