Skinning Help

[Wolf Link]

Any of you know anything about skinning forums on VBulletin?
The skin my site is using...no idea what happened, but the images just died. I've re-uploaded em, replaced em with newer versions, replaced em with my own....everything the creator said I should do, and nothing fixed em.

What I want to do now is replace the skin, but without losing the navbar changes that I've made. *I'm clueless with coding, so those 'simple changes' took me a long time to do.* Is it possible to add a new skin but not lose the navbar changes? Or will I have to do them all over again?

Thanks.
