What is the actual problem you're facing, besides simply seeing that message? is the YouTube IMaGe server, and it is used to serve up the various image elements required by YouTube, including the player's "skin":


Right-click any YT video and set the privacy settings for Adobe Flash Player to Deny and ensure Remember is checked:


If you have problems playing back YT videos, let us know. You can also try Help / Restart with Add-ons Disabled to see whether any of your add-ons is the cause.
