I believe Genesis 3 to Poser utility corrects the lack of expression problem but you need to use DSON to import the figures into Poser before applying the fix.  I can create a fully useable G3 and G8 figure by resaving a new .cr2 DSON import back to the Poser Library.  That is the other option to create a functional figure if you can get working.  I can but I haven't seen other users post their results.
