The producer on cyber hunt has been owing me money for 14 years

Retrieved this contract today.
Reread it...And saw this clause...

This producer has been owing me money since 2006...Obviously took advantage of the young screenwriter i was at this time. Too proud and happy to get hired for the first time. Yes it was for my first assignment back in 2006 on science fiction film "cyber hunt". This person never paid me. I've been asking him to pay me today and he still wants me to wait. He owes me the compensation plus the interests...Almost 14 years.
