Errors with Design Extender

I've recently updated my copy of Design Extender and am using the Power CMS Builder portion of the plugin. When I first uploaded all the info, integrated the database and updated my connection file, I was getting an error:
Fatal error: Call to undefined function virtual() in /homepages/43/d259262383/htdocs/SynikFC/gallery.php on line 1

Replacing virtual' with 'include_once' took care of this (and another on line 5), but now I'm getting this fatal error;
Fatal error: Call to undefined function WA_getCMSContent() in /homepages/43/d259262383/htdocs/SynikFC/index.php on line 23

Just wondering if I'm missing a step... I never had these issues before when using the Power CMS Builder or an older version of the Design Extender extensions.

UPDATE:
After some testing I changed the 'include_once' to just 'include', and then removed some of the file path as there was some local info still on the lines and we're all good. You'd think I'd know better after using the software for a few years off and on...

Chalk up another one to PEBKAC
