Q: Sierra download link not active

Soon after I started to download Sierra, I had to stop so I clicked on the Pause button. I did not turn off my computer. When I was ready to resume, the Sierra download page disappeared right as I turned on my Wi-Fi. I then went back to the App store and had to log back in. Now, when I click on the Sierra download link, nothing happens. The link is not active. There is nothing in my Downloads folder nor is there anything active on my dock. I tried restarting my computer and going back to the App Store, but the Sierra download link remains inactive.
