Thank you very much for playing D4: Dark Dreams Don’t Die.
On 12/17/2014, we confirmed an error that had taken place. Dummy data had been sent out in place out of the actual ROCK BAND DLC. Because of this, we need to temporarily remove the ROCK BAND collab DLC from the store.
We are working as quickly as possible to prepare the proper data for release, so please just wait a little bit longer. Once the proper data is released, we will also explain how users who have already downloaded the DLC can switch out their dummy DLC for the proper data.
We are very sorry for any inconvenience.
