Hi, at home I use my PC which is the system i first registered my synplant on.

But when on the road I use my Mac; so was wondering if my registration will work on that also???

So i suppose the question im asking is.... "Does the registration I purchased work more than once for me on my other operating systems/machines - i.e. Mac and PC"??
