_Justintime_don't warry, be happy! ;-)
I can not say definatelly that this is a mistake in installation, because I did not tried to reinstall your application. May be. I 'll try on my son's PC ;-)
The only thing troubled me slightly - mixer and eql background (say, in Aura skins) are different to compare with nexus opriginals. Not in sizes - this is obvious, but as background picture.
Aura-eql backgroung picture has sliders lines (scales) incorporated on to the picture's "body", Nexus - not.
But I will try to reinstall Nexus skin again, of course, to make this problem narrow.
