You might have said this, just making sure: if EQ2MAP is installed in
Everquest II\UI\myui
then everything else needs to go into this same folder. You do not need to edit eq2.ini (the eq2map updater has done that for you if eq2map is already working). Nothing else needs to be done except for what the individual install instructions of the mods you are installing might tell you. Certainly do not use /loadui (ever).
