Hey Janusdesign!
First of all, thank you for the purchase!
This issue has not been reported before. From the error code it looks like the theme did not install correctly – could you please try deleting it and installing anew? If this does not help, I will need to ask you for admin credentials so that I could take a look at the back-end. You can send those to support@satoristudio.net (no disclosure guaranteed of course).
Sincerely,
Andrew | Satori Studio
