Hi Tyler, from Ron and Leader dog Boz. There are two different keys.There is one for FSX and then there is a second one for the third disk which is the excellerator.
Also, since you were getting the error message that you were getting.retype in the key but if I remember correctly, the letters must be in a upper case. So try retyping the code but use uppercased letters instead of lower cased letters.
Hope this will help you out. Ron and current Leader Dog boz who states"that a service dog beats a cane paws down any day of the week."
