You should be aware that we admins are NOT Gumi. I'd defer to Gumi support, especially since I have no idea what the MST download problem is.

Try uninstalling/reinstalling (assuming you have backed up your game to Facebook), or within the game menu settings, there's an option to "redownload" or something like that.
