Domain Error trying to take certification exam

[Kim in GA]

HI, folks - would greatly appreciate your help.
Studied 'madly' (took my last vacation day, yesterday!), bought the exam, and on entering the certification key, received the error, "This quiz cannot be shown on the current domain."
-I'm at home on a protected network (hubby is an IT geek - firewall in place).
-Rebooting didn't help. Tried on both Chrome and IE 11 - same error.
-I can run the practice exam, but that's probably not secured.

Any ideas? I really don't want to lose my mojo - thoroughly studied and created a quiet place I won't have again for a while

Sorry you're having issues. I think you're going to have to contact MadCap directly. Although MadCap employees occasionally drop by, these are peer-to-peer forums. We users aren't likely to have a clue what to do about this. (Just watch, someone will come along tomorrow who actually does have a clue...)

No problem. Thanks so much
