hi I'm using an old apple G4 dual 1.25 power pc running 10.5 OS. I tryed to upgrade Limewire to pro from a free verson of 4.8 only to find out that i could not use the new upgrade so i tryed to make the old 4.8 verson pro but i dont have tech surport cause i just payed for the upgrade not surport so now i'm in an endless loop is there anyway i can make my 4.8 pro from the free verson without paying again even if paying again would work
