If you have lost access to your registered email, we suggest making a new GrowID with the new and correct email and moving your items to the new account.
You can contact us if you have receipts of any older payments that you have done on the account. These payments can sometimes help to prove that you are the owner of the account.
If the email address that is registered with your account is invalid, and you did not purchase anything in-game, we will be unable to help you recover your account.
Do not hesitate to let us know if you have any other questions!
