Humble Bundle steam keys expired?

I have stuff from humble 4 and nothing has ever expired, must be dud codes from the get go or used by someone

Edit: Hib 6 was my first i think but still have codes and they still work

When you say nothing happens, do you actually get some kind of error message? Steam doesnt usually just do nothing when you put in a key.

There are no keys in Humble Indie Bundle 11. They use direct redeem system there.
Did you login into your steam account before trying to press those "Steam" buttons?
And I mean login at Humble Bundle Page. You have to link your steam account before redeeming games.

"Nothing" can mean a lot of things, my friend - it'd be nice if you at least screenshot what the nature of this "nothing" is, censoring sensitive info where necessary

you already clicked on the right to get a gift link, you can´t claim the same game for your steam account.
use the gift link to claim the game on steam

How your redeeming urls became gift links? If you did not turn them into gift links to give to friends, seems someone entered to your account and stole them.

I also have some old humble bundles that I hadn't registered an account for until now, and I asked HB support about retrieving them since someone else claimed them.

No response yet, and doubt they'll refund them but I still love the site.

They answered and said I was hacked, but they gave all my keys back.

I think it's time to start using more than six numbers as passwords.
