I purchased the game from the Humble bundle, It appears to e version 1.2.6 and when I try to register it, it says that it was accepted but nothing changes. The story still locks me out when I reach the end of the chapter.
It would be nice if some fix was stickied. But at least I had some fun finding one of the titles released last year. Took me abit.

The one forum post that looked similar to my issue was an email fix so I had to register myself to ask.
