Need help with attachments to socket on makehuman model

,Hi! I have a problem, when I try to attach anything to my “weapon” socket nothing happens in the skeleton preview window, and I’ve made so that my level blueprint should find the socket and attach a skeletal mesh to it but instead it gets attached to the root of it, like this: http://i.imgur.com/TefzSAS.jpg

Here’s my blueprint: http://i.imgur.com/hROGepO.png

As it doesn’t even work in the preview window i get a feeling its not the blueprint that is failing. Maybe it’s the | symbols in the bone hierarchy that makes it so that the socket cant be found.

Any help would be appreciated, thanks in advance!

EDIT: i tried previewing both the standard first person and third person with a socket and a static mesh attached to them in the skeleton window, didnt work either.
