Lord, my archive already contains the correct eq2.ini.
Vanyari, is it possible that your friend switched the launcher region at some point which creates a subfolder with a separate EQ2 installation? In that case you would need to install the UI into that folder. Same for Test server installations.
To test whether you really installed in the correct folder you can also type /loadui. If ProfitUI is not on that list, then you got the wrong folder.
