I am just returning my THIRD Rio Karma in seven weeks. Each one arrives, I try to load software, make it though 3 or 4 songs and it locks up. When I call tech support -- they put me through a diagnostic that reports back on screen: BAD KARMA.Even though I contacted them about the problem IMMEDIATELY, by the time I shipped it back and it came back to me -- it was over 30 days and then they would not refund my money. They keep sending me refurbished defective units. I feel ripped off -- and its no small amount of money. If you've had any success either:- in getting yours to work- in gettting your money backPlease let me know at simon@rockefeller.eduThanks,
