The iLok versions of the new libraries, Synchron Player and VEP plugins do not currently support MAS in Digital Performer. [Edit: Apparently fixed in the LATEST version.] In fact, most Mac folks can only seemingly get it to work at all by doing a manual download and install and not using Vienna Assistant to perform the installations. I've not heard reports of whether the Windows versions will work this way, and I am afraid to try again till I hear something concrete, as using Vienna Assistant hosed all my projects leaving them to report "MAS Plugin not found" for all my tracks using them. (A TON OF TRACKS!!!)
Your only recourse is likely to start over again using your eLicenser versions of the libraries and plugins. Reverting for me fixed everything.
If using the eLicenser version, Do NOT try to install the Futanaro Flute freebie, as it only installs via the Vienna Assistant and that installation will break your Synchron Player.
