im really struggling here, i couldnt get onto early access because the code i got was invalid, i thought 'hey ho', ill wait for the physical to get here and sure it will be fine, so now my physical copy is finally here and with the code out of the box its still coming up invalid!! am i doing something wrong or is there a special way to do this?

i have checked all digits are correct, and also tried on the account management redeem codes and playstation store redeem codes.
