Help please

I really like this app. However, I recently changed my password style (from pattern to 4 digits) and the app no longer recognizes my password. The hint is for the old patterned password but the decoy password (when you type your password in reverse and decoy notes pop up) works for the current password! I hope I have not lost all my work, that would be heart breaking. Any body know what I should do? I have e-mailed he developers multiple times but havent had any luck. I will change my rating when this is fixed.
