Urgent (20 min - 1 hour) Help me fix my software's bugs

I have a clip searching tool that currently runs an error connected to the pickle Python module. It may be the central cause of the issue, but it's unclear. I need help fixing this bug and up to 2 small simple bugs that may pop up after. Please confirm you're experienced with Python and are familiar enough with pickle ([login to view URL]) to help. My budget is low ($10-20), as I think it's a simple debug. No more than this please.
