Big Pharma Redeeming On Steam

So I just bought Big Pharma and humble gave me a steam code. I entered it into steam and accepted everything, now I am trying to download my game and I have to download it on chrome (which sucks for downloading things) instead of on steam. If anybody has a solution to this I would like to know how to fix it as I want to play the game as fast as possible. Thanks

Downloading on chrome anyway, I still want it on steam if possible though.

The game will not be on steam until release date, but the steam code you have will be valid on that date. Until then, you have to download from the payment company, not steam. It shouldn’t be that slow though.

Thanks for the reply.
