Cheers for the code mate, think i finally got it sorted.
Couple of things -
-Make sure you link your 3ds to your club nintendo account in the eshop.
-The regestration / download page is a pain to find, i found it on the second banner across on the welcome screen of the club Nintendo page.
-After entering the code i was emailed, I got a code on that screen, which allowed me to download it through the eshop on my ds.
I am now waiting for an email with the codes on so that i can pass it on.
Thanks again.
