JudasIscariot: Do you have any games set to "Hidden" in your account?
PeterC2: Possibly, is there a way to un-hide them?
Go to
https://www.gog.com/account Once you are in your account, please click on "My Collection" (see
this screenshot to see where to click :) Once you click on "My Collection" there will be a drop down menu and one of the choices will be "Hidden" with a number to the side of it. If you have a 0 for "Hidden", please let me know.
Alternatively, you can also try refreshing your account and you can do by going here:
