PTR Servers Missing.

Whenever i attempt to login to the PTR, there are no servers listed on server select. I'm told this issue might be specifically affecting players that were in Cata beta, and it's causing us to not see the servers.

Is there a workaround for this or is it possible to remove the "beta account" from our games so we can access PTR? Perhaps the issue in general is being worked on?

I've participated in nearly every PTR build and it's a shame i have to miss this one due to a technical hiccup.
