There is now a change in the place you collect your rewards from.
It used to be from inside the app, but now you go to this link: http://news.onepiece-tc.jp/serial_campaigns to collect your rewards.
On the first blank, key in your id (found on the top left of the screen when u try to login).
On the second blank, key in the rewards code.
The rewards will be sent directly to your inbox as per usual.
