I launched the game today and everything was gone and acted as if I'm just starting new. I was at level..

Hopefully you had your game bound to an external account (IM30 / google play etc). If so then get through to the point where you can access your settings and log back in with the account details to restore the game.

If you haven't bound it then it is possibly lost. You can try contacting the developers using the in game support. They have a form to fill in with your lost account details (name, state etc). This may allow then to restore it for you. But I don;t know how often this works.

How long was your last login? Were you in a alliance when u logged in last time? If your answer is no to second question, then the game will delete your progress and saved data every fortnight or so.
