Profile hasRegion is not defined

I'm attempting to use TeamCity on EC2 and set up Cloud Agents. When setting up a new cloud profile I'm running into some problems. I enter my Access Key ID and my Secret access key from Amazon Web Services and then press the "Check Connection/Fetch Parameter Values" button I get the following alert dialog:

"hasRegion is not defined"


At this point I cannot continue and I cannot create the profile.

I'm using Google Chrome. When I get this message.

If I use Firefox I get this error message: reference to undefined property "hasRegion", in a dialog alert box.

I tried generating a new access key and tried using that, however I get the same error.  I have checked the server logs, and I do not see any errors anywhere. What might be the issue and how do I resolve it?

Thanks,

Donn
