iTunes almost impossible to use offline

[alelux]

Hi everybody,
when I am offline if I start listening on iTunes a song stored in my hard disk this message appares "iTunes could not connect to the iTunes store. Make sure your network connection is active and try again".
It is a huge problem to me, because I use iTunes during my classes (in places where very often there isn't wi-fi) and I need to restart and change tracks very often! it is almost impossible to use iTunes in this conditions!!!
someone knows how to solve or how to downgrade?
I use iTunes 12.5.4.42
thank you!

Here's a link to a thread with a link to a thread: the link
iTunes 10.4.1 is the last version that doesn't bug you at all about not being online.
The warnings get more strident as time goes on.

There are also many sites on the internet with iTunes downdate how to's
Many of them probably work.
