okay, it sounds like you made these changes through WB (global settings) and did not use skin studio to do these. I'm not sure that SKS has any global skin settings which leads me to believe these were done in WB.
it looks like all of the textures and colors have a "none" option. the font can be changed back to allow the skin to choose the font and all of the sliders have a middle position, that would essentially be the default position. I don't use these functions but it would seem that you would have to also click on the "apply changes" button for them to take effect?
20/20: just do one change at a time and see how you like that change before initiating another one.
let us know if this works
