I've been giving Object Bar a try today, but no matter how I try and load the skins, only a few will actually load. The rest return the following error:

No ObjectBar Theme Definition File (.obtheme) was found within the theme package! Package was extracted but not loaded.
Realoading old theme...

I've tried to load them with the Wincustomize browser, via opening them directly in IE, and by downloading them to my HD and trying to install them locally. They all return the same error.

Two skins off the top of my head that recently did this:
Mcpinty OS X Aqua UPDATED
Mac OS8-9 Jaguar Bar

Any ideas?

Thanks
