Emax

If I save all of my current library to sounddesigner then place them 
on a zip drive which I plan to install in the emax rack how can I 
avoid the dreaded different software rev screen of agravation? Also 
does anyone on the list know if there was a sounddesigner revision 
that supported EII, EIII, and Emax platforms, Also would this reqire 
3 macintosh computers to use sounddesigner on all three?
