So about a year ago i bought the physical version of Skyrim on amazon. I lost the disk but still have the activation code. Also, when i log onto steam and look on my games it doesn't say skyrim or anything about my DLC downloads I also looked in purchase history and it doesn't say anything about me purchasing Hearthfire or Dawnguard at all (i did buy the DLC on steam.) My question is how do i reinstall Skyrim and it's DLC with only my activation code?

Thanks

Activate it on Steam. There's an option in the library. If that fails, contact Steam support.

How do i activate it?

In the library section, there is an option to add a game. It's usually near the bottom left, if memory serves.

Okay, i found my Skyrim!! thanks, but my DLC isnt showing up, where is it? will it install with my game?

It should. If it doesn't, you may want to contact Steam support.

Okay! Thanks for the help!
