Are the Dupont download MTL files not working ATM?

[sketchgorilla@gmail.com]

I've downloaded all the Dupont MTL files and dropped it in to the KS materials folder.

When I try to load them on KS, they just come up as a FLAT RED material ( all of the MTL files from Dupont).

Is it just me or is the DUPONT files corrupted?
