The instructions were a lie, or rather it didn't work the way they said it would.
Basically I updated the server and it won't start now; I shall fix it tomorrow morning hopefully but it may take some time as I'll have to chase forum posts and error messages all around the place.
Summary: TS3 currently not working
I managed to revert to the previous server version and get it running. Will dick around with the update (and add an idle bot so no more kick timers) soon
