I've downloaded the template STRINGS and immidiately went to update Helix and Pagebuilder as instructed. The only one that wouldn't auto-update was Pagebuilder 5.0.9. The updater said to download it and install manually. I did so and I get the error "Call to undefined method BuilderAutoload::loadHelperClasses()".

I tried a few times and decided the template had errors so I downloaded LIGHTBOX. Went through the exact same process and the site gave me the error "Call to undefined method BuilderAutoload::loadHelperClasses()"

Should I not be updating to Pagebuilder 5.0.9 as instructed?
