I FINALLY GOT ALL THE CODES TO WORK EXCEPT FOR THE DESTINY CODE STILL FAILS TO DOWNLOAD IN THE QUESTS.
*****UPDATE: FOR THOSE OF YOU HAVING PROBLEMS WITH THE CODES BEING INVALID. I HAD THE SAME PROBLEM SO WHAT YOU NEED TO DO IS ENTER YOUR CODES THROUGH YOUR ACCOUNT MANAGEMENT IN THE XMB INSTEAD OF THE PLAYSTATION STORE AND ALL CODES SHOULD WORK INCLUDING THE PLAYSTATION PLUS CODE.
I'm having problems with voucher codes too. I got the first two (music unlimited and PSplus). Then I some how lost connection and then got signed out. Which I then had to start the quest all over again. And none of the codes worked especialy the destiny and last of us themes. Which I really wanted. Please fix this problem.
