Cheers Guys, I haven't upgraded for a while, well since moving to 8.5PE. From what I recall, I log in to Cakewalk and they know what versions you have. Actually something I've always liked is that the site not stores the serial numbers for previous versions, but the authorisation numbers. Something I've found quite tidy accessible, helpful S**ts hiotb the fan and you have to reconfigure.
I've emigrated to Vietnam, and importing my old laptop is going to be a killer with duty, even getting the last 8.5discs sent over will burn the pocket, so figure time to use the money it would cost ton invest, and download rather than a physical copy. Sorry Scott, even your old Sonar User guide will have to remain in storage.
