Took a 8+ year hiatus
Last Rock Band I played was Rock Band 2 and I spent 100's of dollars on DLC and now I find out I'm too late to export them to Rock Band 4. It also wouldn't let me play on Rock Band 2 because of the error "The song data you were accessing has become unavailable, and the game cannot proceed without it. Your game session has restarted". Basically, am I out of luck now because I took such a long break? I want to buy Rock Band 4 but only if I got to keep my RB1, RB2 and DLC content.
