I would call Flexi direct and talk to them as I had a issue (not with a broke or lost dongle key) and they were great! My issue was I just bought new software and at the time had a PC and decided on my first visit to an Apple store that I was going to change everything to Mac! Of course the software did not work with Mac and when calling Flexi I was greeted by the greatest company that sent me a download for the same version in Mac and my dongle key worked perfectly. They are good people, they just may want the broken key before replacing but my money is on the fact that they will help you!
