First ensure you are not using skins.
The Ribbon Style comes from the Codejock DLL Files which you must match to the codejock version.
The cjstyle files should not affect the style within the ribbon. I know that sounds illogical.

It is easier to use the sig group ribbon stuff rather than the original stuff I did that may be lurking around still.
It is more upward compatible, even though it is missing some features you will probably not use.
