Problem wid 'folder lock'

i installed folder lock which i was using for some months.......

recently somebody at home mistakenly deleted my user account...........
when i created another user account for me........i found that folder lock asked registeration again........

when i registered it with log in and password.....it opened but this time there were no files that i stored previously,...
also where the files were actually located do not accepting any folder of the same name as them......that means the files though not visible somewhere lying there........\

any help to retrieve the files......pls..............
