I am running 3188 (3/7/07). Program is working fine. Windows installation is within Parallels, not Book Camp. I have purchased an upgrade to 3.0. I have the keys. I have downloaded the program and read the instructions. What is the best way to upgrade with minimum issues? The instructions seem to imply a full installation with re-installation of Windows XP, etc. Is there a way to upgrade to 3.0 from 3188 without re-installing Windows XP from scratch? If so, how? I had to call Microsoft once already for a new set of keys and that is a procedure I would like to try to avoid. Thanks!
