I downloaded and installed the latest version of Flash player (22.214.171.124) yet when I go to youtube it says I still need to download Flash. I double-checked on the Adobe website and it confirms that my computer does indeed have the latest version of Flash player. Why isn't it working?
Sorry I forgot to specify. I run Safari on Mac OS X.
I was careful to follow the instructions you gave to the T, but unfortunately I'm still having the same problem.
