TOPIC: Front End User Panel issue

I have a problem in my DT Register Event in that saving of any edits to records made in the front end User Panel is rendered impossible due to a erroneous requirement for off line credit card details which are specifically not required for my event. I raised a support ticket for this on 13th of March and have made a weekly resubmission without any reply whatsoever. I have updated both Joomla and DTRegister to the latest versions since logging my ticket but neither resolved the problem.

Could I please get some feedback on this issue?
