If you are running an older version of our plug-ins (prior to April 22) or if you are using an iLok to unlock the plug-in, the PACE iLok License Manager needs to be installed on your system (find more info here). If the software is not installed, this may lead to a crash when the plug-in is loaded.
You can download the iLok License Manager from here:
