YouTube: "We're sorry, this video is no longer available"

Do you constantly get this message? I'm willing to bet that you're either trying to watch a lot of banned YouTube content, or you're running Google Web Accelerator. I had this problem before (even with YouTube's own help videos) and found out that it was caused by Google Web Accelerator. All you have to do is get rid of Google Web Accelerator. I don't know that the thing is of much help, anyway. Mine has only saved me about 3 days of time, and I've been running it for over a year.

If you want to check to make sure it's Web Accelerator that's causing the problem with your YouTube videos, try just stopping the thing. Click on the little icon for it, and select "Stop Google Web Accelerator". (Forget about "Don't Accelerate This Website" - it won't fix it.) Then, browse around YouTube and see if the videos come in. If they don't, you're on your own!
