Smush Pro doesn't appear to be active

Hi Team, I've installed Smush pro on jameskitchens.com.au but when trying to access http://jameskitchens.com.au/wp-admin/upload.php?page=wp-smush-bulk it tells me to upgrade to PRO and some features (at the bottom) are still greyed out??? When I click on my WPMUDev console and select James Kitchens it tells me I've installed it?
Side note - when I tried to install smush pro via the WPMUDev screen in the backend of Jameskitchens it didn't work (and showed me a 500 error) so...I ended up installing it manually. Your help would be greatly appreciated.

Thanks Flo
