I have had Libronix/Logos 3 for 6 years now and use it everyday, and would love to upgrade to Logos 4 yet do not have the means. i was told that I can install the Logos 4 programme for free and use the current resources i have on Logos 3 Gold. Is this true and what are the complications and is it worth doing? or is it better to just stick with Libronix 3.0g
