Connector XX on Part YY should have both copper top and bottom layers, but the svg only specifies one layer

First of there is already a part for this:

which has an improved version later in the post. That said, as @roboteach said your zip file is the entire folder which is why the part won’t load. To correct that zip only the files to a .fzpz file and it will work. Doing that indicates a number of errors: schematic lacks terminalIds which causes this:

where the wire connects to the middle of the connector rather than the end as it should. As well in pcb the hole sizes are incorrect (and inconsistent):

which shows in the gerber drill.txt file like this

; NON-PLATED HOLES START AT T1
; THROUGH (PLATED) HOLES START AT T100

The top two entries

T100C0.035870
T101C0.035871

should match the third

T102C0.038000

which is the correct size for a 0.1in header. The 0.035in holes are too small. Running your part through FritzingCheckPart.py flags these errors:

Connector connector8terminal is in the fzp file but not the svg file. (typo?)
