Your account has been sent to studio for fixing ( there is no timeframe )
to subscribe for now, if you install the game via steam and login and play on a character to be sure the accounts are linked , you can then subscribe via steam whilst this gets sorted
steam is the only way to activate a subscription on that account at present, you can wait for them to email you saying it is fixed , but there is no time frame provided on when that can occur
