How do I install the AccuPOSE INFINITY perpetual license if I was a previous subscriber?

The mirrored pose does not entirely match the original pose after executing Pose Mirror in the AccuPOSE panel.

When hip translation control is not activated, the character's hips keeps lowering with consecutive Compute operations.

Why does the character's pose change so dramatically after activating the control points and applying a different training model?

I can't adjust existing keys after I apply Speed Change or Time Warp to the clip, or adjust the project fps.
