My save file is corrupted!

Hi. Im DD player, I knew this game from humble mobile bundle.
I didnt know about cloudsynk until a recent days, So I got the DD key from Humble Bundle hompage, and created the account.
But Immediately later, When I opened DD app, I saw a error message that my save file is corrupted.
I tried to fix this error, but I couldn't.
And, I maked new kingdom and try to login-cloudsynk, there isn't any problem.
But I want to restore my kingdom, I played hard after getting this game, I cleared all of gold challenges including monk gold challenge, and almost of diffiiculty-3 dungeons quests. I played this game so long time.
Please help me!
