The problem isn't limited to the Zynaptiq demo, it seems. I'm reminded of the "iLokalypse" debacle of three years ago. During these episodes, doing anything iLok-related - authorizations, license moves, etc. -- can spell doom. It could be days or weeks before it's all settled, unfortunately, and I don't expect PACE to be forthcoming about what's being done to rectify things. Sorry for the gloomy assessment, but I've seen this movie before.
I have and use many iLok-protected plugins, but I do wish iLok wasn't a thing we had to worry about. Never a good situation when so many products share a single point of failure.
If I were a dev who relied on iLok copy protection, I'd be livid (again). They're the ones who'll be fielding support calls from angry customers. I should note that the Zynaptiq guy has been on the case, doing whatever he can to help. But the problem appears to be out of his control, unfortunately. Sigh.
Cheers,
Eddie
