Well, nuts! I upgraded to the X64 version and now my files are gone! Any ideas?
Got it back! There is a little circle to the right of the schematic you can't open that says "Clone" when you hover over it. This allowed me to retrieve the file!
Darned little documentation on this, though!
Brand new interactions and interfaces. 
Easy to use and quick to get started. 
Perhaps you could write a short HowTo, illustrated with screenshots and post it as a topic in the Tips and Skill section?
