I just managed to get it to work.
I downloaded the master zip file, unzipped everything and went specifically into the expansion breakout board folder to open the project and everything worked like a charm!
And of course, it only worked perfectly on KiCad v4.0.7, as it seems they have changed the schematic library portion in the latest stable release, v5.0.1, which causes missing links for components in the schematic.
Thanks again for the quick replies and assistance!!!
By the way, may I know what is the difference between v1.0 and v1.1 of the expansion breakout board?
