To amplify what has already been posted, you need to edit out **all** of the IK related lines from the CR2. They are:-

1. Within the body part section change the parenting of the foot from BODY to Shin
2. Within the channels section of the body part set the initial values to be zero. You have probably already set the rotations to zero, check the translations. I'm pretty certain that in your case this is what is throwing you off. Note that the value is repeated in the keys section. Although this value refers to animation it will still throw you out if not also set to zero.
3. In the figure section change the foot to be a child of the shin. Then delete all the inkyChain lines.

Hope this helps.
