Need to submit a support ticket

Really disappointed. Trying to add a Support Ticket and the form will not let me add a category (there are none to choose from) and so the validation kicks it out. Just spent $100 on the Nation theme for developers package. Lots of good things about the theme, but a clean install is giving me errors in shopping cart and I need some help. If not, I would like a refund.

How is it no-one keeps up to date with eCommerce Drupal themes anymore? Very discouraging. Is there any way to really contact this developer?
