Hi, winrob! Earlier I have downloaded the Nebula 3 user guide, probably from someone here on this forum. Don't know why it's not available under the FAQ section? It's perhaps a bit old (2007), but probably some useful info anyway.
Here you can get it (link expires 2 weeks from now, January 8, 2013):
I noticed that I must have something wrong with my Nebula 3 pro because when I open it, I don't see a list of my libraries on the GUI. It's just written INIT and I have to click on INIT to see my libraries. Anyone else has that?
