Portfolio Gallery won’t display anything after upgrading to pro

I have been working with this portfolio plugin and have created projects for viewing. I liked some of the feature options available in the paid version so we bought it for our client’s site. With the free version I can see the projects without issue. I downloaded the files, they downloaded automatically then I downloaded them again via the confirmation email, for the pro version.

As soon as I installed the pro version of the plugin the portfolios stopped showing all together.

I looked through the forums, followed the steps others have done.

Note: At present all files are locally on my work machine and not on a test site.

Troubleshooting steps already taken:
Uninstalled the plugin, reinstalled the free version, inspectected the page and saw the portfolios, then reinstalled the pro version and it broke again.
Disabled and reenabled the Huge IT Portfolio plugin, no effect.
Disabled all other plugins, no effect.
Re-enabled them one at a time, no effect.
Restarted the localhost server, cleared cache, no effect.
Gone through all settings, updated colors an fonts to ensure I’m not simply missing white text on a white background, nothing became visible on the project page, no effect.
