I need help opening a drawing.  The references are broken and I don't know how to repair them.  Usually SW prompts me to browse for the missing files and repair the references but it won't do it this time (probably because my coworker saved it with the references broken).  I've tried right clicking and opening the part, and it will let me fix THAT reference, but the crossed boxes remain on the drawing.

Any other troubleshooting tips?  Using: SolidWorks 2013.
