" Addit Pro "

My free trial expired and requested an unlock code number. If unlock number was sent, it may have got deleted
accidently.  Through e-mails and letter, which came back with my check, undelivered. I would very much like an 
answer from some one. I think "Addit Pro" is a good  thing for us simmers who have a hard time installing ACFT
inFlt Sim X.  Why can't get I get another code number to unlock it ?  I still have it in my PC. If I can't use it, I may as well delet it.  I need ans. from some one.  Thanks.
