GIMP Plugin Registry

Hi everybody,
i'm new in this forum and i have a problem with the script-fu web-o-tine under the os windows XP sp3.
Since i have updated gimp 2.4 to 2.6, the script doesn't operate, each time i've got this error message :

"Error: set!: unbound variable: html-file ".

What can i do i don't know programming language ? If someone can help me thanks a lot .

(sorry for my english if is not very well)
