Parts of correct imported Rig are missing

[hankey]

Hello there,

i have a seriuos problem with my rig.
When i imported my Character to blender, everything was fine.
Clothing was okay, Character and mesh were okay also.

Now after editing my character a little bit and after texturing i set the rig back to visible
and now there are a lot of parts missing from the rig (pose).

there are only the bones left and i have no idea what i can do.
can please anybody tell me how i get my rig back. i worked for a week now on this character and now i can do nothing.

i already checked the layers, but the parts are still missing.
i used the gaming rig.

thanks for your help!
