WorkBuddy photo organization keeps throwing file path errors. Anyone else seeing this?

I came across that step-by-step WorkBuddy tutorial claiming it can automatically organize folders. My first thought was: isn't this exactly what I need as a wedding photographer? Before delivering the final photos, just sorting hundreds of RAW files according to the workflow takes up an entire evening, leaving my back in agony. But after installing it and trying twice, both attempts got stuck at the same point.
