App Store Update Button not Working?

[ArtOfWarfare]

I'm currently running OS X El Capitan Developer Beta 2. When I check the Updates tab of the Mac App Store, it shows me that OS X El Capitan Developer Beta 3 is available, but when I click on the "UPDATE" button next to it, all it does is show the button recessed, and on mouse up it returns the button to normal. It never shows me a progress bar of any sort like normal. It doesn't do anything to indicate that it has received my mouse click.

Restarting the Mac App Store did not help me.

Is anyone else having this problem?

Is there an alternative way of downloading and running the installer for Beta 3?

Edit: Just discovered the command line tool softwareupdate that comes with OS X.

softwardupdate -l

Shows that it knows that the update is available.

I'm running softwareupdate -i -a

Right now, but the last thing it printed out was

Finding available software

And that was 3 minutes ago now. I wish I had included the -v flag, because I have no idea if it's working or not right now.

Edit 2:

It just printed out this:

Downloading OS X El Capitan Developer Beta 3

Guess my internet is just slow as hell...

Does nothing more than open up the MAS and redeem a code. So it still goes through the MAS, which seems to have a very buggy UI.

Running

softwareupdate -irv

On the other hand, bypasses the app store and gives you progress notifications on the command line. And since it doesn't give control back to you until it's done, it's way more comforting... you don't feel like you're just pressing a button and then being entirely ignored (which I'm pretty sure I am when I just hit the button in the MAS.)

i tells it to install
r means to install all recommended updates
v means to be verbose (which, from what I can tell, all that means is that it prints out percentage process notifications.)
