I'm using WinXP. I have had Adobe Flash player working for years. I just updated Adobe Flash Player to ver. 9.0.124.0 on 2 computers and now I can't view Youtube videos on either. I have JS enabled. I can view with IE, but I don't like IE. I'm using Netscape 7.2.

The IE and Netscape installs are different. You must choose the browser version you want to install:

I downloaded the Netscape version and loaded it after I used the Adobe uninstallerand closed all minimized programs (Netscape/OE), as required. I also ran SubInACL.exe (subinacl.msi) and the executable installer( Install_Flash_Player_9_ActiveX.zip) as instructed in the Technote (Troubleshooting Adobe Flash Player installation for Windows). Youtube videos Still don't work In Netscape 7.2.
