IIRC, there was a Python script change with P8/PP2010, that may explain why it is not working. 

Now I have tried running the Advance Figure Randomizer in PP2010 and it appears to work without any problems for face morphs.  Are you sure that you haven't selected other body parts when creating you INJ?  Also, if you want to include other dial-morphs, you do need to specify that when creating the INJ/REM files.  Otherwise, you wiil wipe out and remove previous morphs.  Maybe if you outline your workflow through screencaps, we might notice something you are overlooking. 

And, as les posted, you can try contacting them @ RDNA.  They do have an excellent track record with customer service.
