@hellocataner These are some basic question to identify the session you played and to check if something went wrong. No need to personal attacks or the mentioning of the well being of people that want to help you and find out what went wrong.
Apart from that: Did you played only the seafarer expansion or did you play the game using the cities and knights expansion. The Achievement is only awarded when playing the scenario using the seafarers expansion. Have you tried to relog (log out and in again)?
