I am the webassist support person.... So if I'm answering your questions you are getting support.
Anyway, if you continue to have issues you can post a US phone number or Skype contact information and I'll do screen sharing with you to help you identify what is wrong with your Dreamweaver site settings to help you connect to the database.
It is almost always a bad setting the testing server section of your Dreamweaver connection. If you do want a refund I can of course process that, but you might as well let me get it working for you first so you can properly evaluate it.
