I heard from D3D (Ralf), gave him this thread link, maybe he'll take a look?  He mentioned making it a CR2, but I think we tried that, unless this utility by Nerd above is what we needed to make a proper CR2?

 

Just heard back from him. He's found the problem and the fix will be in the next version of Morphing Clothes. In the meantime, keep pressing Enter during loading, when you get the message about the invalid file. You'll have to do it several times, but eventually the clothing will load.  Then resave the CR2 to the library.
