Multi-level navigation plugin destroys 6wks of work

I’ve been searching for a way to get some dropdown nav in my site. Today I installed “Multi-level navigation plugin” I didn’t like the looks of it so I un-installed it, I reinstalled saved copies of my header and css and now I have about 6 horiz. nav bars…can’t find them in any editor pages,,,grrrrr!

Any help?
