i cannot install my simcity 4 deluxe program on my vista computer due to rejection of the 20digit code printed on a sticker in the wraped box which it came to me from Amazon.com. this code is in the format of: xxxx-xx#x-xxx#-#x##-xxxx. is this the correct format as wherin x = letter, # = Numeral? Why is it after 10 attempts I still get the message that I need a valid code? What recourse do I have? What Can I Do???
