I have Luminous working as guest mode, using AquaDX remote, and I am unable to create a new save file. When I first tried to create a new save, I accessed some other player's save file (we used the same 20 digit aime). When I changed the 20 digit number in aime.txt and try to create a new account, I get this error:
I tried several different 20 digit values but I always get this error unless I use the values that belong to the other player. Any advice on what I should try?
EDIT: Found the issue! Just had to go to the service menu and make some changes.
