Xsi 5: Reset Actor is not working

Reset Actor is not working in xsi..
What is wrong? I have worked several hours on my rig and now when I want to go to default pose I can't do it?
I can see it because when I mute the envelopes the model is jumping to a different pose.

If the envelope deformers are constrained to other control objects, then Reset Actor won’t work. In such cases, you should use the Actions > Store > Transformations - Current Values command to store an action containing the current transformations of all your deformers and control objects in the reference pose before you move anything, and Actions > Apply > Action to return to the reference pose.

Thank you.
