Unable to download and install El Capitan Public Beta 5 10.11.6

I am unable to download and install El Capital Public Beta 5 10.11.6. The download from the App Store begins, gets to 149 MB, and just stops. The progress window just goes away and nothing happens.


I have re-tried the download many times. The first few times, more of the file was downloaded, but it still quit as noted above.


I have deleted the plist file in the user library for the App Store, and the mac has been restarted a few times as well.


Anyone have an idea what might be going on?
