KeepVid allows users to download videos from YouTube and other video sites for free, and it enjoys great popularity among people. Although it’s such a very popular online video downloader, Keepvid is still not working occasionally. Here are some of the situations.
I can't use KeepVid or any other Java applet on my browser
I am running Mac OS X 10.7.5 Lion. I was always able to use KeepVid on Safari, but after updating to Java 7 Update 21, I'm always stuck at Loading Java Applet and the window to allow Java to always run from KeepVid never pops up. I have enabled Java on Safari preferences, I've allowed apps to be downloaded from anywhere under Security & Privacy, made sure I enabled Java activity in the browser under Java Control panel and I even lowered my Java Security to minimum and did a clean uninstallation and reinstalled Java. Nothing has worked, and the problem extends to FireFox and Chrome as well. What should I do?
