G String, don't know why you trashed my response. My process worked for me ....FACT. Learn to respect others, even if they don't agree with you.
In the event that my process is not supposed to work, consider idiots luck. Either way I have all my profiles and performances from my old PC on my new PC by copying over the the backup file, not folder.
It does seem a bit heavy handed, but you have to consider it might not work for someone taking your advice. Then they might potentially lose their library, which involves a lot of hours fine tuning many profiles.
I too got lucky with various working methods not prescribed for rig manager, but will now follow the recommended methods. I could not afford to lose the live set!
