Joomla! Template AT Transport - Item Support

I installed the quickstart and did everything perfectly. When I try to view the back and front end I just get a Fatal Error message. Ive been through all of the Akeeba Backup troubleshooting guide and nothing outlines my problem. How do I get it working. It seems overly complicated just to get sample data on a template

The backend Joomla log in works but after I log in I get an error message as well
As we said we are not able to log in to the back end as after log in we just get another fatal error message. So I am not able to install the patch. I installed this on a new clean server, there has go to be an easier way to install sample data. If you are not able to fix the problem I need a refund for this purchase. This is going on to a couple of days now without what we purchased installing correctly.

You want me to post the log in details of my server on a public website????????!!!!!!
I need a refund. The PHP version on my server is fine.
No its been 5 days and just to get sample data on a template. I need a refund.
