Keep a hold of it, it happened to me on my 09, it was over Xmas break lol COBB sorted it for me NP. Its the same AP but it does not recognise the ECU id that is all.
Z is still relatively new and the new releases of ECU handles need to be incorperated to the 'accepted' database for the AP to see it and know it is able to install.
This will help
