You will need to update these apps with the Apple ID they were bought with. Do you remember it and the password? Have a look in Settings - App Store (if upgraded to OS6 it will be iTunes and app stores) and see what ID you have here. You can sign out of this ID and sign back in with the right ID.

Thank hoy for you'd reply. I am indeed all updated. Sadly I just cannot remember the password for the original account. I also tried changing the password hoping it would let me in, that was never gonna happen :/
I have also relieved a message to tell me the email address I started up with is no longer in use. This all happened AFTER I updated to ios6!!!
