I am very disappointed in the service from "Crispy Driven Pixels" the makers of the "Ethereal" Photoshop plugin for the leap controller.
They just gave me this .zxp file that extension manager complains about and fails on.
No install instruction, and their web site sucks.
I lost $30 on this plugin.
I'm mad.
And they are supposed to be a member of some Leap developer program too.
