trying to export curves from Maya 2013 to rhino to use with grasshopper

hello all:

for some reason, exporting curves from the new release of Maya, Maya 2013, is being very problematic for me.

I am trying to export curves as an iges file for use in rhino and grasshopper...it seems they changed the iges extension to a DCE file type..

Is anyone familiar with how i should export my work from maya to rhino???

any insight or sources would be greatly appreciated...
