Farm 133 Theme Pack not displaying on site

After network installing the Farm Theme Pack and activating the list of themes on Mysite, the themes become available at the site level. Once I select and activate the theme, the site goes blank, the dashboard goes blank, and every screen goes blank. I can't even look at the site dashboard to deactivate the theme.

How do I solve this issue and regain access to the site? I've network deactivated the theme on the Super Admin dashboard and still no luck.

Any help would be appreciated.
