I'm afraid that I can't download it directly from Download button bellow "You own this game" line, nor from the Download button from my Library.
The line still "Nothing is available for download yet.", even I hit the Download button from my Library.
The file is shown to be downloaded only when click to "Download Now" button in the front page.
It also happen to Tower Tycoon.
Hope you fix this soon.
nor this button. This raises a fear that claimed games in my library may not downloadabe after the sale/freebie ended.
