Go to your Dying Light Dockets profile, link your gaming platform (the one you own the original Dying Light on, e.g. PSN, XBOX Live, Steam) and make sure you have really played the original Dying Light (2015) game for a while, otherwise the banner will not show up.

The banner won't show up if you used software like SAM or was idling for hours using some other method!

In addition to the above, turn your Addblock add-on off at the Dockets site and refresh it, please.
