Yeah...I paid and then followed the download link. After a while I went to email which brought me back to same page and tried it again. I went ahead and downloaded again and it says it will not update.

But I finally figured it out after some further troubleshooting. The problem was that I had initially did the demo and after buying the game and downloading, it tried to install it on top of the demo. So I had to uninstall that, redownload, and now it opens up to an animated title screen that wasn't there before.

I'm gonna try a playthrough now and see what happens. But I think it should be fine from this point. Thanks for replying and from what I have played already I love it. 

I'll update if I encounter the same problem.
