New Server - mission doesnt load after role selection

[Wete]

Hello,

Ive had several issues whilst trying to configure this server... but ive slowly made progress. Now, when I get to the role selection screen, I select a role, click "ok" and the mission starts to load. It then throws me back to the role selection screen. Ive had a dig through the logs and have found several things that may or may not be relevant... but I cant seem to find any advice. Any help would be much appreciated! Its a dedicated server running liberation. Here are some of the errors from the log:

Server error: Player without identity Peter (id 1388008578)

No more slot to add connection at 089144 (8919.7,14458.3)
