Hello Kevin,
When asking something related to a Forge component, it is always better to post in the Forge Component Support, as all the members are notified about the question.
I received your PM and took a look.
The Account SID that you should define in the Configuration page was being hardcoded to an old test SID. This was causing a mismatch between your authorization and the one expected by Twilio for the SID being used.
I fixed this and uploaded a new version of the component.
If you update the component, the demo, after configured, should work. At least in my tests, I was able to use the demo successfully with a new "try" account from Twilio.
If you find any problem, please, let us know.
Cheers.
