In Little big planet 1 and 2 i had all the dlc , everything. I sold little big planet 2 then bought the special addition because i missed it.The special edition had dlc that i already had but , when i reinstalled lbp 2 it reset all my dlc , all of it apart from the ones that came with the special edition.How do i get my dlc back? I even have a little bit of proof because some of my levels include dlcs such as mgs but im not allowed to edit them( because apparently i haven't purchased them)

Also i have 2 accounts and one of them had all the lbp 1 and 2 items on it so how do i get it on to my new account?
