itunes locked

Hi Folks,

Just recently I have tried to transfer my itunes library from my laptop to my LG K10 so I can listen to my library anywhere but with little success.

But i managed to find itunes on my Android but it asked for security answers for which i don't remember them and now i find when i click on my itunes app on my laptop screen it states "my file is locked" , any ideas how to unlock it ?
