Humble Bundle ,Trine 2 didnt work :| what about you guys?

Restart steam goddamnit

Restart steam - helped for me.

Reboot steam...

Happens with keys sometimes...

get yourself a PS4..a lot easier to handle..if you have problems to activate a game on Steam ;)

steam has to restarted for it to show in the library and reason the box is blank is because no name for it has been put in the system of steam for it probably.

yeah it did that for all of the games i activated today ( not only from Humble Bundle ). Just restart Steam and they will be in your library. Some problems with their servers probably (i hope it's becouse there will be some massive sale or event tommorow :D ).

Steam is throwing a fit with everybody redeeming HIB9 keys, just restart steam and it'll be there

You don't need to restart steam. It will be in your library in a few minutes.

I have a different problem - What when a game will not install?
When i try to install Eets Munchies i get error "invalid install path"

Other games install fine, and the install path is the same :/

blow up your PC & start from scratch. the game should appear without any problems
