I clicked Claim, but no files show up to download.
Try exiting and re-clicking on "Download or claim" and see if the file shows up.
OK, once I clicked "Download or Claim" again the file showed up and I could download it. But even now if I click "Download" at the top of the page where it says "You own this game", it takes me to a download page where it says "Nothing is available for download yet." Weird. Thanks for the game and bonuses!
