Display frontend product modification using MP Frontend

I've been following these threads:

https://premium.wpmudev.org/forums/topic/general-step-by-step-on-how-to-create-a-store-with-the-same-architecturefunctionality-as-etsycom

and I've downloaded this plugin and followed these instructions:

Using the default Framemarket theme from WPMU I am able to display a themed frontend product editor like in the example tutorial. However I would like to use this in conjecture with Marketpress in my own theme.

I tried to copy the code from the register-store.php into my index.php file, but the page still comes up as unstyled at all. Can someone please assist me in getting the product registration frontend page to work with my theme?

Thanks
