I tried only switching the region on my origin account from Italy, to colorado and it worked for me...first attempt with Italy as location get me an error, second try with colorado worked fine, and i can find the game on my library, and also Beta access is unlocked.

Hi there, unfortunately that's correct. There's more to it than just the IP location. There are other factors taken into account when trying to activate the game like Origin region settings, payment handle and probably others. Your activation attempt will be blocked. EA is thorough with their region locks.
