I know is no due to you, but any clue about what could be the problem? JA Support is quite terrible...
Here's the clue: Joomla relies on certain events to occur in the process of building a page for the components to have a chance to insert their output. If the template does not accommodate for those events, there is no way for components to interact with it and do what they supposed to do.
I empathize with your situation, but I have a problem in principle with providing free support for mangled paid templates.
If they have the nerve to take money for sub-standard product, they should have the time to provide adequate support.
