I have sonar platinum, lifetime member. I also have some older versions including version 8 on a DVD that I am occasionally using. It just looks like keeping platinum installed and authorized may be more trouble than it's worth for me.
I have signed up for the Panu and Bapu forums.
I am also going to look into seeing about the installer files or downloading them. I have never deleted any from my computer, don't really know where they are.
I am an Okie but I have a lot of Boston ties and I have always liked the fact that cakewalk is based in Boston.
