spamis - WOW, you are using version 2.4.3. Do you realize how old that is?? Sorry but there is no support for that. Nothing I have posted in this thread will apply to that old Joomla 1.0 based version. On top of that, looking further I see that there are no previous orders for your username. So you need to do two things:
1) make posts using the username that you purchased DT Register with
2) upgrade DT Reg on your site.
