I decided to try again installing the update from last Fall (build 204) after upgrading my GPU. It hung during startup while apparently trying to load EVERY VST plugin on my computer (most of which I will never want to use with VMS - they are for my music production software). To get VMS to start I had to find and rename the folders where the plugins are stored. Now VMS loads (but WITHOUT the few VSTs I DO want to use with it - which worked fine in build 143) - the update apparently deleted any preferences I had set.
But I can't figure out how VMS knows where to look! There are NO search folders in the preferences dialog box (not even one for VMS's own plugins, which it seems to find and load anyway), so why did it search the two folders (and a dozen or so sub-folders) containing VSTs I use for Cubase, and how can I tell it to stop?
