Unable to join dedicated servers?

Hello. For some odd reason, I can join and create regular servers, but when I try to join a dedicated server, it gives me a message saying, "Sorry, but you cannot join the server at this time. Please try again in a few minutes." Or something along those lines. Any ideas on why I'm having this problem?

Have you tried to join an empty, open non-private/gold, server?

I think it's a left over mess from whatever they did with the LIVE services the other day. There have been a couple of messages I got about people not being not being able to join our XF server. But we don't have any bans in place.

So I guess maybe try again in a couple of days. There have been time when I was having the same trouble. And somehow it just fixes itself in time.

I've tried joining empty Gold servers, still didn't work. Also, I've had this problem since I installed Halo 2 that it's been like this.
