No video since security update

Ever since vista did an security update on 7/11 alot of streaming video will

not play. One site in general tells me to update my media . well upon trying

to upgrade it tells me have a newer version than what the update offers. not

sure if its ok to list sites that i can give that I know will not play. Wild

america is the one that told me to update. but other sites such as music

jesus will not play (red X is all i get). I have went through security

settings and have enabled some of the stuff that pertained to media player

but still no luck. So if anyone has had this problem let me know.

thanks
