This is the error I get, and there seems to be no way around it...
It works on other computers, so I think there may be a problem with browser or firewall settings. This computer also has Covenant Eyes filter on it.
Sorry for that error!
Covenant Eyes was an issue with some of our launcher flows some time ago, but I haven't seen it become a problem in the last couple years. Have you tested alternate web browsers on the problem PC?
