Were you able to convert the files without having an account with SonicStage or do you still have your old account? I got rid of mine because I thought since the store close I would not need it.
SonicStage as I mentioned in my post stated music files still work after store closed. It did not mention you had to still have a n account and even if you needed one that would not make much sense because the store is closed. I am not able to play them anymore and I tried different conversion tools and they haven't worked.
As I also mentioned I did read the other posts.
