Fish game:hook drop problem

alright…im trying to make just a little game for fun, it will consist of you being a fish and haveing to move around while collecting objects…but you have to dodge the hook that falls from above…well my problem is with the hook dropping…i can get it to work but every now and then the hook just freezes…i have alot of variables and alot of rigging…i will attack the .fla file…and if you have any questions or want to know where i put a code, i will be able to help…but as of now, i have no idea why the hook randomly freezes, thanks in advance for trying to fix the problem,
