So a friend deacitivated, had second thoughts and reactivated his account but now when he goes to log in it says error code LM-25, basically it says he has no account

He checked his status and its active/continuous but still cant log in, on 2 different puters.

He contacted customer support who told him to delete his member name from the pol log in screen then re-enter it and it will fix it, which he did and it didn't

Anyone else have this issue before and know how to resolve it?
