Hope This Helps
I just have a feeling its something in the way you are installing the actual UI - so I attached a screenshot of my file structure so you can see how a working one looks - I have eq2map installed as part of my custom set as well as some Fetish pieces and other custom stuff - all in a folder called "Tester1"
so my ini looks like this :
cl_ui_skinname Tester1
cl_ui_subdir UI/
