Flash player doesn't work?!?

[Guest]

I've installed and uninstalled many times!  I have a macbook 10.6.8 and my last update killed the flash player (along with a few other things).  Apple said to use Safari, however Flash player will not work.  All videos are simply a black box with no audio or video.  I've even tried to use it with Firefox.  Same problem. 

It claims to install correctly.  The process flows just fine.  Yet when I try to use it or verify that it's installed, I get nothing.  HELP!!! 

(and Thank you!)

Make sure "Allow all other plugins" is checked.

It's checked.  I figured it would be something simple like that, so I appreciate your help.  Unfortunately, it's already checked.  Any other suggestions?

I've gone through the Adobe trouble shooting pages several times.  Still nothing.  I'm officially confused!

How to perform a "clean install" of Flash Player in Mac OS X

Trash the old plugins and do a fresh install.

[Guest]

This is so very strange!

I followed the clean install info EXACTLY as it said.  When it was completed, nothing would play, despite the facet that the "allow other plug-ins" box WAS checked.  So I said to myself, maybe if I UN-check and RE-check it something will work.  While it was UN-checked a you-tube video did play.....so I attempted another....nothing.  I RE-checked and restarted the computer.  Nothing!  Every website (tried HBO, Youtube, and Hulu all on Safari AND on Firefox just in case)......all tell me that I need the "latest version of Adobe Flash player".  

I believe it was HBO that said version 10.2 minimum and I believe the version I"m attempting to install is 11.9.

And I thank you kindly for any additional suggestions.  I promise you that I'm following these directions word for word....something is clearly wrong!
