Hi,
I think you meant a VW. The VM rather refers to the VintageMeter plug-in.
This is a common problem running both Vintage plug-ins under Mac applications. As you know Mac applications require memory settings. The Vintage plug-ins are very hungry for memory due to extensive graphics.
Just give all your VST applications enought maximum memory and make sure that no unused huge application is running when you open your VST application.
This should solve the problem and all meters and knobs should go back into live.
Regards,
