I too am having an issue, I tried using Soldiertech's GUI which is based of all the core files from this GUI. So it works like a charm except one issue, my Planetmap will not work properly. As in I am unable to change it to a new map.
It gives me an "unable to load file Anarchy Online\cd_image\textures\PlanetMap\false" error and I am unable to sort what is causing that.
I did a fresh install on my 3rd hdd, patched it, and did the instructions to the T, and it still gives me an error on the planetmap so what am I doing wrong?
