Hi! i havent visited gog.com for a while and now it is all different to what i was familiar with - i want to just browse the games in my collection but i cant find how to do this - if i go to the menu under my username and select "games" it just goes to the gog home page. is it the case that i can only access my library through galaxy now?

Hover mouse pointer over your username until the menu shows up, click Games.

HTH.

You may need to clear the browser. There has been updates to the site and others have had issues until they cleared the browser. It should still be under username-games.

Somebody had the same problem, but they didn't report back to say if it's fixed for them.

In the meantime, your library should be under this address:
