Make sure you followed the install instruction exactly. Especialy make sure you extracted the archives to the correct place, as it seem yau are missing the GUI-definition files at the place they need to be. (Make sure you have the updated Anarchy Online\cd_image\gui\default folder after extracting)
P.S.: The 17.1 update of the skin is completed internally and will be released on patch day. Will of course try to get in some of the requested changes until then.
