where do i install my chains of promina patch , treasure one and , rise of xalrtiha...? any quick help woudl be gret because now im playing wihtout em.. is it bad? will i lose my guy? thnx

its not bad, you wont lose your guy... Go on FFXI menu, than go to register ID (I think), and you will see the sub menus and click on the one you want and then enter the key

No idea.

Shouldnt u install all the pathces directly into ur ffxi folder?
