I have downloaded Macromedia Flash's latest version, I know I have because i
can see the animation that tells me "successfully installed"

However, on every site outside of Mcromedia Flash, It still says I need to
download it. For example, I can't watch any Youtube videos because it says "you
need to have Macromedia Flash player installed...but it is. This is happening
on EVERY site that needs to use flash player. Except this site??:confused;

Any help you can give me. I have tried leaving my computer for days, but still
no change.
