The token provider was unable to provide a security token while accessing...

i have installed servicebus 1.0 on a virtual server and it appears to have installed correctly and i can see the service running.  I followed all the steps here on msdn. Then on my dev box i setup a visual studio project that is a copy of the "write your first application" @ http://msdn.microsoft.com/en-us/library/windowsazure/jj542433%28v=azure.10%29.aspx

When i run the program i get the following error:

"{"The token provider was unable to provide a security token while accessing 'https://vdev2k8:9355/ServiceBusDefaultNamespace/$STS/Windows/'. Token provider returned message: ''."}"

while searching here i have followed the example on installing the certs on the dev/client machines.  herehttp://msdn.microsoft.com/en-us/library/windowsazure/jj192993%28v=azure.10%29.aspx

if i drill down into the exception i see that i'm getting {"The remote server returned an error: (401) Unauthorized."} as the base exception.

i have not setup anything dealing with users/accounts, access keys/tokens etc.

Here is the output from "get-sbnamespace"
