#1 - Please backup your old JPremium config file and generate a new file!
#2 - In this version player gets a new unique id (UUID)! The unique id is not premium or offline id, it is randomly! Why? The older version causes issues for the unique id, and from now the unique id is must be randomly. If you do not want a random unique id, please set 'fixed-unique-ids' to 'false' in JPremium config file.
If you have any doubts, please contact with me in private message.
