frontpage

i have a web i created in frontpage with fp extensions enabled..i have a host that allows it..i have posted my site and the search works good...i changed the site and uploaded the index page without using frontpage to publish my page..now the searchdoes not work on the site...i go back into frontpage to publish it from there and i keep getting an error that says cannot open "we80.cnf" no such file or folder...the properties of the page say it is looking for the "all" word list and it does not exist..what have i done and how can i fix it?
thanks
