Partially set up account

I have an AWS Account that was partially set up via the S3stat Secure Setup Windows app. I could not complete it because each time I click Continue on the Role screen, the endpoints would display for a split-second then take me back to the AWS tab.

Now I have an AWS account that's partially set up. I can't manage/remove it in the web interface because I get a message stating:

"This endpoint was configured using the S3stat secure Setup application. You'll want to use that to modify it"

and I can't manage it within the app because I can never get to the endpoint screen.
