How to turn on javascript for flash

[FONT=&quot]Hi, I encountered this problem when I tried to access youtube.com from this computer of mine, a really old one, one’s that working on a 30day trial of Windows XP. And I couldn’t view any videos on youtube. Youtube gave this message: [/FONT]
[FONT=&quot]Hello, you either have JavaScript turned off or an old version of Macromedia’s Flash Player. Get the latest flash player. [/FONT]
[FONT=&quot]I already have Macromedia Flash Player 8.0. Isn’t it new enough? [/FONT]
[FONT=&quot]And how do I turn on JavaScript?[/FONT]
