Slate VMR doesn't load anymore [SOLVED]

Hello,

I am using Wavelab Elements 9.1.0 for Mac I recently upgraded from El Capitan to Sierra, and now I get the following message when I try to load one of my mastering presets:

"The following plug-in could not be loaded successfully. Verify if it is properly installed.

‘Virtual Mix Rack’"

The AU version works just fine in Logic Pro 10.4.1. The VST version works fine in Audacity 2.2.2. I have re-installed the latest version of VMR and rebooted my machine. No change.

VMR worked just fine with WaveLab under El Capitan, otherwise I wouldn’t have been able to save my presets with it. Is there a fix available? Does VMR work under WaveLab Elements 9.5?

I went into the Plug-ins list, deleted VMR from the list of “do not load these” and had WaveLab rescan all of my plugins. It seems to be loading fine now.
