Thanks for your input. I was never able to locate the KMA files. I suspect that the update from Hoster 3.303 (on Windows/XP) to Hoster 4.32 (on Windows/XP) bypassed a fix previously noted by a Hoster user on the Hoster help blog. Instead, I located my current playlist/song database backup and restored them and then rebuilt them. Everything worked well after that.
