Error on uploading template

I loaded the 'demo data' during the Jamoola installation using your Hot Start zip file (as per PDF), and it was a clean installation with an empty destination folder. The error message I received was when I attempted to install the Hot Cars template through the Jamoola control panel.

Why would you need to install the Hot Cars template through the Joomla control panel when after completion of HotStart everything is done and installed?

I am visiting your site now and see everything is set up correctly. You don't need to do anything more regarding template installation. Just change our content with yours and enjoy!

I was following the instructions as per the PDF regarding template I love the template design and instructions, I look forward to making small changes. Do you have a plain copy of the red background for the header so I can add my own cars and text?

When you open PSD file in PhotoShop (or GIMP), you can disable car layer and put your car image inside.

Sorry to be a little naive. Can you please tell me where to find the header file (acme leasing)? I can only find .jpg images and these are not layered. Thanks
