After hiding the free games in my games library The Witcher 2 is not shown either.

In the catalogue it still shows me that I could redownload but after clicking on this button the game still is not in my library yet.

And of course, it is not in the folder with the hidden games :)

This is most probably the cause, so unhide the games and it should reappear again.

Is TW2 your only non-free game, by any chance? I think there's an odd bug that occurs if you have only one game not marked as hidden.

Sometimes a Game would disappear when I changed the sorting from 'date of purchase' to 'by title'.
A reload would fix this.

Dunno what causes this.

The Witcher 2 is the only non-free game in my library.

It also appears after unhiding at least one of the free games. It is just a bug but at least I know that I can redownload The Witcher 2 and I hope that after buying a second game this problem is solved.

Check your PMs for a second game. :)

Oh, I say, good form! Good form, indeed.
