I've been having a similar problem, the game stoped responding like two days after the wings came out so I unistalled it after I tried trouble shooting. But, when I tried to redownload it all I got when I clicked on the Download one was this...

I'm not sure what's wrong, I've been playing this game for almost half a year now...I think and I've never had any problems with the game not responding, I mean It just like closes once you click the icon. Noy sure if this is the right place to put this but it seemed like it was the same problem you guys were having...Hope it gets fixed soon, promised to finish and export a map after Christmas... </3
