Pi Musicbox not showing files on NAS

When trying to browse my mp3:s on my NAS (Samba), I can’t see any files. Somewhere on this forum I read that Sqlite should be updated. Will it solve my problem? How do I do the update?
Should I download an update - from where?
How can I update Pi Musicbox - with Putty?
I’m new to this and need som advice and steps.

EDIT: I just had to give the IP-address and it worked. //
