Adobe Flash problems

[Garry Driffill]

Getting really peeved with this at the moment, Youtube wont play without this and other applications and such.

It asks for an update when trying to play anything on YouTube, I install it, it says installed correctly and go to the page again and it says the same as it did before i installed it.

Ive restarted it after installing the software, ive wiped it clean off (Flash Player) and installed it again and it still says NO.

What am i doing wrong?
