HELP !!! I have license version of Pro 2, but on old laptop. So, for the new laptop do I have to buy only the update Pro 3 (49$) or the Full Version(99$). I hope The update doesn't just download the update of a Pro 3 because then I might end up paying 49+99 for no reason. Why is such a basic thing not clearly written on the page ?? And Nothing about Old S2 and Pro Compatibility either !! HELP !!
