Cannot open assembly due to configured component.

Hi

I have an assembly that just wont open (solidworks crashes/stops working), I have traced the problem to a part in a sub-sub-assembly I think. I cant open the part (software crashes) either. The part is not big and is a simple cable with a few configurations (no routing). I cant see how i can fix the problem without creating a simpler part and redoing my whole top level assembly. Has anyone else had a problem like this? How can it be fixed?
