Help for some reason my GOG has the items mark as in Kronen instead of my usual canadian dollar. Since I cannot see my Canadian dollar I chose US dollar and yet when I open GOG it is still showing as Kronen. How can I change this. THanks Ray

It's a common bug. It is usually solved by adding any game to your cart, then going to checkout. Your preferred currency should be back. It's not necessary to complete the purchase.

Or you could delete your cache and cookies in your browser.

Or refresh your account: https://www.gog.com/account/refresh

Or switch to another language and/or currency and switch back. Has solved this problem for me.
