eq2.ini is already there.. so now what?

[divsaty]

Hi I have heard from almost every player that ProfitUI rocks!! So I thought i would try it. I am following the instruction and I get the step about creating the ini file in the \Sony\EverQuestII folder.. and I am surprise to find there is already a document with the same name eq2.ini in that folder.. the lines read
cl_ui_skinname EQ2MAP
cl_ui_subdir UI/

so what next.. can I add the profit lines to this file? And yes I already have the Eq2map autoupdater installed and I am guessing this is part of that. So any thought would be greatly appreciated.. thanks... Divsaty
