My KyCalc Password

Hey there, I forgot my 4 digit passcode. I still know my long alphanumeric password. But I cant get to the password page. I mean, it is perfect for the app, but I cant use it anymore and there are some really important files in there. How can I reset - or find - my 4 digit password? Please help asap..
