AE CS6: AEGP Pro Import Error (5027 :: 12)

I'm trying to open an Apple Motion project in After Effects.  I'm using ProImport, it recognizes the file but before loading it I get an error message that says the following: 

(5027 :: 12)  After Effects Plugin Pro Import:  "Fatal Internal AAF/OMF/XML error.  Please contact customer support." *0:1134) (5027 :: 12)

And then it doesn't import anything. 

Any ideas as to what I need to make this work?  Is this a known bug?
