I think that your problem, or at least part of it, was that the T7_2 server, when I first set it up, was in 60fps for the 66 mod. When I started it I did not notice because it does not show in the remote starting. When I myself got the message that I was not qualified to enter the server when I tried to, I immediately knew what was wrong and went in and changed it but I guess that you had rebooted yourself out of connection by then.
Ahh that was probably the reason. When I started IGOR, the T7_2 server was already up but with about 40 mins left so I tried to join. Probably at the same time you did.
If you have the time before the Watglen race Feb 7, I can set up the server for a short testrace to make sure that you can join.
That would be helpful, probably best to do it on one of our race nights so that we don't clash with any other users of the server.
