You need to be able to login to DesignSafe before any of our tools will work. Did you go through the DesignSafe portal to get to the TACC create an account? You need to get TACC to sort this out. As you cannot login to designsafe to submit a ticket, you will have to login to the tacc portal again and submit a ticket (it is under the consulting menu). TACC and DesignSafe are staffed by the same people, so they should be able to help out. Get back to the thread if you are still having problems and I will try submitting one on your behalf to DesignSafe proper.
