Okay, my Minecraft won't update to 1.6.4. Neither does it want to update version 1.6 and above! This is why I'm stuck playing 1.5.2. I have a 1.6.4 folder with the jar, the json, file, anything you would see in an ordinary versions folder. My launcher keeps saying "Will be updated" and after a while, the dev console shows this:

If you're wondering why I want to play 1.6.4, the Aliens vs Predator mod hasn't been updated to 1.7.4 yet.

Also, the launcher always gives this:
Data\.minecraft\libraries\org\lwjgl\lwjgl\lwjgl_util\2.9.0\lwjgl_util-2.9.0.jar for job 'Version & Libraries': Couldn't connect to server (responded with 403) but have local file, assuming it's good

^I didn't copy all of it cos that's what it keeps saying (403)
