I've never used an iLok Dongle or have any idea what it is. After I went through all of the steps and opened Studio One 3 Pro it said that I (still) had to activate the software with the iLok Dongle.... I know Slate Digital is fine equipment I have the SSD4 (and it was not easy to activate either, always have to call to get help), but that program does not require the iLok. I don't plan to use too many of this type of plug-in - Presonus' stuff is pretty dang good. So I unistalled the software but when I start Studio One 3 I still get the error message that I need to activate the software with the iLok Dongle. How do I remove this software from Studio One 3 Pro on a MacBook Pro 13" running Yosemite?
