Error 21051 Unknown product code


New member
I am looking for Knife Edge tech support. I have a new computer and was transferring and reinstalling all my programs. I got RF6.5 installed and working fine, then... my brand new computer crashed hard! I did a recovery, but now the program gives an error when I run it. I tried to reinstall over the top and deleted it and tried again... same error! How can I get this to run? I have the controller plugged in and all the serial numbers at the ready (xmitter, Heli Pack and RF6).

Thanks for any help
