My internet connection works fine, but whenever I try to sign into sites like YouTube, I receive a message asking me to download the latest version of JavaScript. I have attempted repeatedly to download it, but it never seemed to show any progress. Once, it did display a loading bar and said it was installing, but, even after rebooting my computer, YouTube still wouldn't work. Oddly, when other sites embed YouTube videos, I can play the with no problem. It's just when I try to use the site itself that I have trouble.
