Hi,
​First you have to download SP Page Builder Pro from here
​https://www.joomshaper.com/downloads/extension/sp-page-builder-pro
​Then you have to install it. Go to administrator-->extension-->install
​After that you have to active it.Input your email and license key to SP Page Builder -> Pages -> Option (on the right) -> License & Update (input your email and license key) -> Save and Close.Your License Key is located in your Dashboard.
​Then Clear Joomla and Browser cache.

I don't think that's the trouble, I have this installed since last year and I just updated this about a week ago.

Did you follow my rest of the instruction specially activate page builder and clear cache?
