Solution 1:
Your download is being blocked by something on your system, typically a browser extension or addon or your AntiVirus, firewall and other security software. Some of these browser addons are still active even when your security software is disabled. We suggest temporarily disabling all AntiVirus, firewall and other security software including browser extensions and addons and then trying the download again.
Solution 2:
Clear your cookies / cache then try again.
Solution 3:
You are getting logged out while trying to download. Something is deleting or not saving your cookies. Can be security/privacy software or privacy settings in your browser.
