Not being able to reply on forum

Yesterday I received a message I have no active game time left to write on the forum but I’m on a 6 months auto renew.
Still I’m not able to reply topics. I haven’t tried logging the game yet but I hope it would work tonight.
Did I get banned without any warning? I don’t think I did something ban worthy.
Thanks.

Check if your subscription is actually active (payment could error-out etc). If it is try relogging on the forums.
