Locked out of ffm?!?!?

we’ve a instance called “free foto messanger” (ffm) about my ipod touch…i noticed they had the latest thing where you have access to a passocde to your app (this was a time back) consequently i carried out it…next i gone the iphone app and additional it once more but my personal passcode wouldnt work…i only tried the idea again but it surely still doesnt function (and i am aware i continue to know the right passcode)

any tips/solutions for this problem
thanks ahead!:)

I will reset the ipod.The app might have a flaw in the container.
