Lost server key, can't hold new key

I've had to rebuild my hosting server. The data drives were backed up but not the users saved game folder which is where the d0si key is stored. I know that now. I keep getting the "there is already a signed private key for 0" after a close. I've played a couple of games through it before closing. Waited weeks at a time to keep testing. What am I missing? I've deleted the key multiple time, nothing works. When I delete it and a week goes by, it does say a new key was generated successfully and supposedly saves it. I see a correct time stamp on the file when it does "save"
