Not sure if this goes here but,

Youtube would not let me view videos. It kept saying "go upgrade!" and when I clicked the link it didn't go anywhere. I decided that it was my flashplayer so I went to the adobe site to get the newest version. (10)

I downloaded it and a manager window came up saying it was finished. I closed the window and read the rest of the instructions on the webpage. It said it would take me to a confirmation page when it was done, but it never did. And I can't find the program on my computer. But when I go to the add/remove programs list in the control panel, it's there.

And YouTube still won't let me watch videos.

Does anyone know what could have happened?

I hope you rebooted after the install, that sometimes fixes the problem. Also, try uninstalling it from "Add/Remove Programs" and then reinstalling.

Install here (http://get.adobe.com/flashplayer/thankyou/).

Uncheck the McAfee scan, and click agree and install now.

What ever it asks you to do, agree, okay, whatever it wants, download, addons, any of it, do it except the McAfee scan (Unless you really want to). But I don't recommend it.

Go here (http://www.adobe.com/software/flash/about/) to see if your flash installation is working. If you see the animation, it means you have installed it correctly, if not then you can try again.

It started working after I shut down the computer.
Thanks!
