They have two servers now. If you played previously your game with 5 badges will be on the Pro Red Server. I am guessing what you did was select the Pro Blue Server which means on that server you start from the beginning. If you go on Red server your save while still be there.
If you are on the same server and your game has restarted unlucky. Don't think you can do much about it since the game is still in BETA glitches are to be expected.
Hope this helps.
