I installed and followed the directions.
I have Bitcoin and PayPal payment options.

I chose 1 option and then tried to change to another payment option, but clicking on the button did not do anything, so I cannot change the payment option.

EDIT: Just noticed the TABS are also not working "Product Description" and "Reviews"

I looked through the forum and noticed a post about the jquery issues, but I dont have that option, so cannot try to fix it myself.

Can you assist

(I think the template looks amazing and I know it will improve my conversion rate... )

Did you check this topic:
www.flexiblewebdesign.com/forum-virtuemart-2-template-puremart-support/523-the-easiest-way-to-solve-jquery-conflict-issues

You can apply that method, it is the easiest way to resolve the jQuery conflict problems.
Please try that, and if no luck, provide me your website URL and let me take a look at it.
