Hello peashooter sorry to hear you have this problem, I came across this when the game first came out (on a forum somewhere can't remember) and if I remember correctly the numbers aren't well printed and an S can be taken for a 5 and a 1 for a 7 and vice versa.
My copy isn't too bad and I can see the difference with a mag glass but if you can see clearly what they are but the codes not working then GoGamer could be right.
Sympathies if this is so but perhaps the replacement may be OK couldn't they "test it" on a PC first it wouldn't take long to see if can load; if it can't they have done themselves (and their customers) a favour by finding out it doesn't work.
Anyway all the best with it mate
Regards - Mort
