I'm totally lost...

[Anakreon]

When I open the eq2ui.xml and edit the groupwindow and then save I don't seem to notice it saving a groupwindow.xml file into my custom UI folder as I had understood would happen. Also upon seemingly perfecting my groupwindow in the UIBuilder I "guess" I got it to work in EQ except for the fact that the entire window was solid black, except for the "search for players" button which turned out to be a spectacular white box.
Any ideas as to what I'm doing wrong here?
