How to obtain updates/expansions

[RedRhinoRock8]

I purchased Hammerwatch on Humble Bundle - Not steam Key version. Game is in my Humble Bundle library only. So how do I update game with expansion V1.3 or any other patch or expansion. Thanks for any help.

Sorry for my english but here is the point: go back to humblebundle, click on you name's account on the right top side of the page and you will have all your bought game. Ask to download it again it should works.
If not, ask to redeem it on steam, it will works (100% sure, i just did it after searhing a solution here.
Have fun dude!
