Can someone help me with the tasks?

Hello, does anyone know how to clear bought of the Lieage 2 tasks? I am trying to make accounts but the tasks are rejected because "i didn't register an account", but I did. Does anyone who cleared the task can explain me what am i doing wrong or tell me how to make a proper account that will not be classified as "non existent". Thank you!

i will start play this game about next week..then we can hook..

never played it ever but will try
