User not found

My friend just reinstalled the game after a long time and when he tried to login using his old account email it says user not found. We are pretty sure that the email used was the corrrect one since we can still check his past purchases on toram and also the Account registration mail. Is it possible that someone changed his email? or can you even change your account email after registering for an asobimo account?

 

this sounds like the player data was deleted.
you should contact the devs, they should know what's going on.

if a player doesn't login for more than a year, the player name becomes unlocked so others can use it. as far as i know this should only free the name but not remove the player data. especially when it is linked to an asobimo account.

you did link it to an asobimo account, right?
because if you didn't and the "registration email" refers to a google account, then the player data is deleted when it is cleared from the device.
