had this problem for a week where server slots where full and ping was 9999.
After working with the fine folks here, I went on my own to find out in the server tab, there are 4 icons; start/stop, restart, trash, and cloud settings.
Now make sure there are servers available for sale, as trashing yours during a "sold out" time will leave you server less till they add more. But, if there are servers available, trash it, start a new one on your cloud (free) and it worked. Had to do this twice, but my server is up and running now. Maybe a loading glitch when I first installed the server.
