This isn't the first mention of it, others were posting about this earlier. Might need to yell at Steam support. I wish you luck.

here restart no help;)
we had problem with my friend with dlc for battlefield bc2.. support solved our problem.. but you have bigger one.. good luck ;)

\That's the* problem

This happened to me too. The game was installed in the shared games list of one of my friends. I hope this will be fixed automatically soon.

Oh, have this problem too... Activated a key 2 days ago and a gift today, none are in my library... The gift also appears in friend activity, and when I try to activate the key again, it says "product already own"...

are you using the family sharing option? cause i think that causes some problems with some games.

I got same problem too, created a ticket but they still not response.

I'm not sure if it's the same problem, but someone gifted me aerena recently, and after I claimed the gift it took 1 week for it to show in my inventory :/

just turn off the sharing and restart steam?

Same problem with a key 2 days ago, says i already owned the product, send a ticket and still nothing...

Maybe if you weren't a filthy brony Gabe Newell would answer your cries.

At least you'll have more time to play Euro Truck Simulator.

so you were already sharing it from someone else and then activated a copy. sounds like you found a bug in the system if thats the case

The magical and wonderful thing with computers is that almost everything is tracked and logged so despite your lack of confidence, I'm sure it'll be resolved.

If your story is true, then they'll be able to see everything you've said and correct the issue. How long it takes is a totally different story.

Steam also stole me a game

Guess I won't be activating family sharing until they debug it. Good to know!

Did you redeemed a game which was in your the family sharing shared games and it dissapeared?
It did happen to me and my gf the another day... Trine 2.

I have to do what support told me, but it seems a bit hassle. I will do it tomorrow.

I could put here what support told me, but i won't take any responsability if someone messes up everything.
Just ask and i will write it here.

Have a nice day.

happened to me too

activated Vanguard Princess, it shows in the market transactions but not in library

try making a support ticket

real happy end :) <3 steam support.

Here is what Support told me. And it worked very good:

·Exit Steam.
·Please open Internet Explorer, Safari or Firefox and type steam://flushconfig then press Enter. (If asked to allow this website to open a program, please click 'Allow' or 'OK')
·When prompted by Steam to reset your configuration, please click 'OK' to confirm.
·Once done, login to Steam and re-test the issue.

Success!!! ;)

And this, just in case you have multiple installation folders. I didn't need to do this step:

If you have multiple installation folders for games doing this process will remove them. You will need to add the folders again in Steam so that your games will appear as installed.
In order to add these extra installation folders please do the following:

1. Open Steam.
2. Click Steam > Settings (Preferences on Mac)
3. Navigate to the 'Downloads' tab.
4. Click the 'Steam Library Folders' button.
5. Click on 'Add Library Folder' and add the directory that contains your games.
6. Click 'OK'.
7. Restart Steam

Have a nice day :)

"I have repack your second gift"

Good English

My problem is worst because is a key not a gift or something and Steam Support is joking with me:

"Retail copies and other digital versions of this game cannot be registered through Steam. If you wish to create a shortcut to this game in your Library list"

Same problem here but with a key and a gift (Steam stolen me 2 copies of Terraria)

So sad :(
