Why the hell do people post this sort of thing in the Discussion board?
You would have had to scroll right past the Support board to get here too. I don't even know.
Support board for technical issues.
But next time, before you post, make sure you've googled your issue and tried all the logical things like making sure your client is up to date.
Also what do you mean by "not letting you in a tourney"?
Do any other rooms work for you?
If you're able to connect to other servers, but not the tournaments, it means that the tournament is full (I'm assuming that you're talking about the automated, 500/750 TC ones).
If its not the automated ones, or you have any concerns, post here.
