Quote - I'm back to poser: I need to know how to use this soft too! Problem: How to solve this bug(?) when loading Aiko3 with Poser7?

You can fix it by editing the CR2 to change the parenting of the feet (which were mistakenly saved with IK on). I think DAZ may have updated the files at some point, so redownloading and resinstalling might make it go away.
