Problem while trying to change 1st job.

Hi,
I'm new and I got a problem while trying to change the 1st job.
I did the Assist quest and it's told me to defeat 10 Aibbat and come back to him, I came back to him and it's told me the quest is completed but I saw that I'm still Vagrant...
What is this problem, and how can I fix it?

I have no idea if it's belong to here or not.

Thanks~

Lol did u read the site? u dont need to do all the quests,just click on "DUTY OF THE (Ex:ASSIST) accept it then talk to the npc again to complete it.

I will open a new char and I will try it when the server will be on.

Thanks.
