I feel your pain. I've been trying to master the trax, and it's not being nice with me.

I'm not sure I totally understand your problem, but...

If your character includes the translate values (the outliner is your friend) then I'm guessing the error is within the trax.

When you have sub-characters, you also need to add the pose in the Trax under their bars. Say you have the follwing in the trax after you hit the funny button with a stick figue and an addition sign:

>Model
>Sub-Model1
>Sub-Model2

You need to add the pose not only to the Model's section, but also to the Sub-Model sections, such that:

>Model
[# Pose #]
>Sub-Model1
[# Pose #]
>Sub-Model2
[# Pose #]

Otherwise, check the character's value's and recreate the pose, and if all else fails, re-create the character. Well, that would be what I'd do.
