Update - Amazon will be switching over the online documents to HTML in the next few days.
There have been thousands of hours of connection streams successfully working off the AMIs since launch a few weeks ago, and we're reasonably certain the GUID issues are not blocking anyone as long as long as the online setup directions are carefully followed. We are no longer doing manual GUID removal, as it should not be needed with a properly set up AMI.
That being said, please continue to reach out to Jax on these forums or PM for any GUID or auth related questions or issues. He can follow up wih direct support if necessary during PST business hours Monday to Friday.
