Need to register TB studio 5 on new computer

How can I install the studio version 5 on the new computer I’m using without having to buy a new version of toonboom studio? I want to continue using TB studio 5 which is compatible with my macbook loaded with the 10.5+ operating system. I will buy a new compute in future but not immediately. I want to continue with my animation projects.;action=display;threadid=5846;start=msg22723#msg22723;action=display;threadid=5853;start=msg22738#msg22738
