Joomla! Template AT Elearning - Item Support

Hi,
I just bought and downloaded the Extended license for the AT Elearning template.
After dowloading it I extracted the files and got the " at_elearning_joomla_template_install_package ", the zip file.
The big issue is that when I try to install it from the Joomla installation option (the one you drop the zip file in), it says me that the plug in is installed correctly.
Now, why is it recognizing it as a plug in and not as a template?
Also, it isn't showing up in the plug ins neither!
Obviously it isn't showing up in the template list, so I can't use it.

I'm currenly using the free version of the same template, ATlearning, may be that the issue is that I have the free version installed?
Of course I can't delete all my previous site!
You are telling me that you sold me a template that cannot be installed by the Joomla installer like every other template?
The only way to install this template is to srestart from zero???
I have a site with existing data and, as I said in my first comment, when I try to install the template package via the install function, it recognizes it as a plug in, not as a template, and does not give me any option to set this template as default! This is the issue!
