That appears to have solved the problem. The file compiled locally with no errors.
yay 
glad we got you up and running - sorry for the bumps 
i'm still not clear on how this situation might occur (this could explain it but not if you've never installed WB v1.4.0 or prior).
when you get around to it, i'd be curious to know what happens after running Particle: Reset Environment - specifically whether or not the ./tmp directory is successfully created and if not, what errors pop-up.
