Just curious 3D Outlaw ... did you run your clothing set through Wardrobe Wizard at all before bringing it into Morphing Clothes?  Reason I ask is I just tried it with a set that I converted manually from Alyson 1 to Alyson 2 ... and then added the GND-Anastasia morph with Morphing Clothes. It appears to load into Poser Pro 2012 just fine.

So now trying to see if it might be a combination of two things here.
