Temporarily disable popup blocking software installed on your computer to test.
Allow YouTube.com as a trusted site in your Firewall software.
Ensure other applications like Quicktime, iTunes, Real Player, or Windows Media Player aren't set as the default streaming application, as this might affect the video player.

If the flash uninstall reinstall does not work this maybe due to a Microsoft Windows Vista permissions issue.
