Motionbuilder 2012 trouble with poses

Hello

I’m starting to have trouble with poses layered on top of animations. I am taking a saved pose from one file and applying it at the start of the animation (full body on a layer) and the pose applies nicely. The problem happens when i play animation, the Ankles seen to be locked in the pose shape. the rest of the body moves along naturally. The odd thing it just started doing this yesterday, and for the last 2 months it was working great. i have made many Cycles, and ins and outs use the pates pose on animation with out a problem. Not sure what changed or how to fix it, any help would be great.

thanks

Is your animation keyed without Reach on the T/R for the ankles, and are the poses using Reach T/R when you paste them?
