I found that I needed to copy the C:Program FilesCommon FilesSony Shared as I believe all the copyright info is kept in the OpenMG folder below ..Sony Shared
Once I had copied all that I could over (complained about one exe being in use), I started SS, and selected a track - it told me that the file wasn't quite correct and it need to do a restore, SS started the restore automatically (I had never manually executed a backup - so not sure where it was getting the restore info - maybe just realigning the DB)
I then restarted SS, selected a track and played the track successfully - and even had the correct checkouts noted
(Just checked out the Ojbsir.exe - looks like that's what SS kicked of - not sure if it would have worked if I hadn't copied over the contents of the ..Sony SharedOpenMGprocfile dir)
