Pray for future availability, that's how we solve problems in this country.

Obviously you didn't try "everything" that you claim you did.

Do you have the stupid Google Web Accelerator? If so, then
dump it, burn it, trash it, disable it, get rid of it, uninstall it --
do everything you can to get as far away from it as possible.
Trying to bypass GWA with "Don't Accelerate this Website"
will not help you whatsoever. That being said.....

If YouTube is slow or stuck, and you get advice from people
to install, change or update things:....DON'T. Your computer
and YouTube were working perfectly fine before, right?

It's never a good idea to go fooling around with java scripts,
firewall settings, flash players, antivirus utilities, registries,
pop-up blockers, different browsers, or things like that.

The first and best option should ALWAYS be: don't disable,
erase, uninstall, separate, alter, download, install or change
anything. Doing those will only make matters worse for you.
(Of course, you should get rid of GWA.)

You should also keep in mind that YouTube frequently shuts
down many of its servers without telling anybody, in order to
update stuff. If that's the case, your problem should correct
itself within a few hours or by the next day.

Whenever YouTube seems stuck or displays strange things,
empty your "cache" of all "temporary internet files", "cookies"
and "history". Things will probably be okay afterwards.

If you're not sure how to do this, or if you want extra tips on
how to make YouTube run even faster (all without having to
install, buy or change anything), then click on my avatar and
email me. I will lead you through "cache" clearing and my
other tips in easy English with full explanations.
