Can I export Green Day: Rock Band to Rock Band 3?

We're sorry, but after 5 years of availability, the Green Day: Rock Band export offer has expired. You can continue to enjoy the Green Day: Rock Band experience on disc, and if you'd like to add to your Rock Band 3 or Rock Band 4 library you can purchase Green Day DLC by visiting the in-game Music Store, or by searching the Xbox Live Marketplace or PlayStation Network store.
