Verify the PIN was entered correctly. A pin is not case sensitive and is alpha-numeric.
Retype the PIN. Make sure that you type the correct characters. The following characters are frequently mistaken for one another:
|•||B and 8|
|•||G and 6|
|•||U and V|
|•||Q and O|
|•||The letter O and the numeral 0 (zero)|
|•||The letter L and the numeral 1|
Make sure the PIN has not already been used to obtain an Office for Mac Product Key. A PIN can only be used once to obtain a Product Key. If the PIN has already been used, you can log into your account with your Windows Live ID to access your Product Key or you can check your email for the confirmation mail you received when the PIN was first consumed to access your Product Key.
