Defined in the context of another assembly?? help?

Hi guys,

Recently My hardrive broke and I needed to use our off site back up to get some files back.

Now when i try to edit part i get this message - "This part has features defined in the context of another assembly you can edit the part but no make any external references to the componets of the current assembly"

Speciciallly I am trying to line up holes using the concretric tool and it won't let me select the edges and points to do this.

How can I fix this problem?
