any plugin didnt load

[spajdr]

Hello
Maybe im stupid, but i read FAQ how to install a plugin.
I downloaded classicvert addon, unzipped it under UI directory.
I created eq2.ini
put this inside:
cl_ui_skinname classicvert
cl_ui_subdir UI/
(tried it in reverse way)

Thats should be all, no?
Well it didnt load, default skin still loads, but if i do /loadui, it appears there, i can choose it, but all numbers are wrong and after restart default skin is loaded, what im doing wrong?

I have US version.
