Trying to run PubSubActivities sample - underlying connection closed

I have installed WFManager 1.0 and all pre-reqs on my Windows 8 Ent machine. I then went into the Workflow Manager Tool\1.0 directory and ran the configurator and then the TestServiceHost.

I went and downloaded the PubSubActivities sample on codeplex and changed the base address to the address I saw displayed when I ran the TestServiceHost.exe.

When I do an F5 in the example, it blows up in WorkflowUtils.cs when it is calling the PublishChildScope method with an error that says:
The underlying connection was closed: An unexpected error occurred on a send."
and
The handshake failed due to an unexpected packet format."

I'm new to the workflow manager so maybe I need to setup some ports or something like that...I'm not sure.

Any ideas?
