Hello Cameron.
 
	With the Gizmo plugin beta version, I had SkyMaxx 3.3.2 on 
	Sierra running. But Gizmo has now expired. I do not know why this is so. 
	However, I believe that a purchased software should work. If there is a 
	problem with Sierra, you should solve it. This is not the task of a user. 
	With Freeware you can still have understanding, but not with Payware. So I 
	ask you to find a solution right away. 
 
	18.11.2016 Continuation of my research:
 
	PS: Now i have downloaded this Gizmo plugin from this link.
 
	https://dl.dropboxusercontent.com/u/948813/Gizmo/binaries/Gizmo64.plugin-16.11.03.1645.zip
 
	now it works.
 
	You could have simply communicated this link to the customer. The official version of the Gizmo website does not work.
 
	Regards
