I bought this program today and started to run it at about 8AM. It is now 11:45 PM - almost 16 hours later - and it is still chugging along. Says it is at “434 karma” without any explanation of what that means. How long can I expect this to go on, and is it repairing as it goes? If I were to stop it so I can get back to my files, will I have wasted these hours and have to do it all over again? Please can someone explain this to me? Thanks
