Workflow Manager Suspends Workflows - "Invalid JWT token"

Hi,

I've installed Workflow Manager with the default settings described in this Technet article:http://technet.microsoft.com/en-us/library/jj193514.aspx. Everything seems to install just fine but when I create a very simple workflow test on an "Announcements" list which simple creates a Workflow History entry. However, the workflow immediately suspends with the following error which seems to be some kind of an authentication error. I am running the workflow logged on as a site collection administrator which is not 1. farm administrator or 2. the service ID that I input into the Workflow Manager Configuration Wizard.I also DO have profiles installed, the user running the workflow DOES have a profile and I DO have the App Management service application installed. In addition, I rebooted the SharePoint VM after the install

Given that Workflow Manager, Workflow Manager Client 1.0 and Service Bus 1.0 are all running on the same server as Central Administration (since I only have the one SharePoint VM) perhaps the reference to "SAMEORIGIN" in the error means something?

I've installed Workflow Manager with the same instructions on other farms in the past and not had this problem and wondering whether the June 2013 CU has introduced this error. . .

Please help!
