Wont let me leave beta

Minecraft is a good game, but it can have a LOT of bugs.  Making the game have weird glitches etc, but it is an amazing game! I had a glitch myself on Minecraft, where I could not leave the Beta. And the only thing I don't like about the game is that in Beta, you can not play with other people unless they are on the Beta too, or play on servers.

Did you follow the steps in this article?

Yes, but somehow nothing worked there were ways to exit, I tried all of them. They didn't work, the last thing was about a command prompt it didn't work. Nothing had worked so I decided to do a bug report. Also (edit) I did uninstall and reinstall Minecraft, after leaving
