mountain lion up-to-date redeem code says 'this code has already been used'
I have a problem with the code I was sent from Apple for the up-to-date program - I received both emails - I followed the instructions, opened the pdf with the password supplied - copied the redeem code and on my first attempt to redeem the code in the mac app store I received the error message "this code has already been used. Each code may only be used once."
I definitely did not try to redeem the code previously - and I followed the above steps within minutes of receiving the emails from apple.
I did the claim through the Australian localised Apple site if this is helpful?
Any assistance very much appreciated - very annoying!
