Gary,
In the window that says: Vienna Instruments AudioUnit-Server Interface (With the Show Window button) there is a mini menu in the top left hand corner where you will find a SAVE SETTINGS option. Here you can save whatever is loaded in a given instance of VI. It doesn't matter how you have set up the instances: it will save a single instrument if that's all or a full matrix. You can also load what you have saved from here as well.
That way if things disappear you can retrieve them because it's a save within VI as opposed to a regular DP save.
Try it - I just tested it and it worked fine.
