El Capitan download stuck "waiting"

Hi. I am trying to get El Capitan beta to download on my MacBook Pro. I successfully redeemed the beta code but noticed that the download had not completed. I opened the "Purchases" section of the AppStore, and see that the El Capitan Public Beta is stuck "waiting", and has been for over a week. My MBP has been plugged-in to the power adapter the whole time.

Anyone found a remedy for this?
