Hand Winch Cable Damage - Supercheap

Hi
Went to use the hand winch in anger and as I pulled the cable in a section that was frayed got jammed between the two feet (pulling mechanisms). Due to it being frayed it can't be forced in or out of the winch.
Any thoughts how I can pull the cable out? Was thinking of disengaged the feet and using the car to pull it out?
Also, do I need to replace the cable or just not us that section in the future?
Cheers
