I am a little late replying on this and by now you have probably either fixed your zipper, torn it out and replaced it, or said to heck with it and left it for another day. Anyway, here are my thoughts.

I have found that “frozen” zippers on dive bags and boats are usually the result of the metal slide (car) corroding. I have had some success alternately soaking them in vinegar, rinsing, and soaking in WD40. I wiggle the a little each time. I have done this dozens of times and win more often than I lose.

If you replace the zipper make sure you have both plastic teeth (chain) and car (slider).
