I got a new computer. The new Intel NUC i7 model, on which I installed Windows 7, which is what I have on my i5 laptop as well. Obviously, I want to run Buzz on it. I copy all of my machines from my laptop, and have been installing VST's one by one. I just decided to try to open some old BMX files to see what VST's I'm missing most desperately. To my surprise, this happens:

So I re-download Matilde Tracker 3 in hopes that the file was just damaged or something. Apparently not so, because when I open Buzz and try to load said machine, the same message pops up again.
Does anybody know what's wrong and/or how to solve it? Is it a setting somewhere?
