Anyone else having trouble with the teex site?

[fork]

I was doing the courses, everything was going fine but today nothing will launch. I've checked and made sure to disable the adblocker and pop-up blocker for the site, still nothing. I press "launch" on any one of my classes in there and the browser just hangs there spinning doing nothing. I've tried firefox and chrome. Are any of you doing any of their classes? Any problems getting them to launch? I'm trying to figure out if it's something that's changed on my end or something on their end.
