I'm not sure I understand your problem. If it's what I think, you have to add the new collection to Vue, so that it knows where to look. To do this, in the object browser, there's a small icon on the bottom left corner, with a blank page. If you mouse over it, you'll see "new collection". Just click here and point to the place in your hard-drive to where you downloaded the extras. From that moment on, Vue will include this folder in the object browser and you can load objects from here.

Was this your problem?
