Can you help me rescue my 2009 Houdini. Apparently I didn't push the zipper pin (on the right) far enough into the zipper box (attached to the left, the part marked YKK), and zipped up. Appears to be one or two teeth/coils "off" where it should be. Noticed the zipper coming undone from the bottom. Tried to unzip but could not. I had to use the Houdini as a pull-over for the rest of the trip.
Is there a trick to unzipping, once the teeth/coils are misaligned by a tooth or two?
