ACF weapon issue

I have tried re installing svn and zip. i have restarted everything i have 720 revisions on svn. i have done all i can think of.
the issue is the gun is linked to the ammo and it is shooting and doing damage but there is no muzzle flash or noise.
if i walk in-front of the gun it dose damage/kills me.
i have made cars with acf.
it also says i am in version 569 and the current one is 571 and i cant find 571.
im out of luck and ideas please help
