I must be an idiot! I can't work this out... I created the UIta directory under skins and copied the contents of the zip file into it, the structure is the same, there are two root folders Basic and UIta and the contents are the same as the unzipped file contents. But in the web admin, when I go to the properties of the Orbiter (also a web dt366) the only entries in the drop down are:
Mobile Phone Basic
Mobile Phone MO
Mobile Phone Monster
Small UI Monster
Even after a regen, there is no UIta... same for all my other orbiters....
I'm using 0710 if that makes any difference...
