from the Helproom - you'll get more help here.
First of all, why did you use WSFTP to publish your site? If you want to use any of the special FrontPage features you must publish to the server direct from FrontPage - if you use an FTP transfer the site won't work. I notice that you say you only published some of the pages - had you previously published your whole site to a server?
You say that the countless hours spent on your site are all for nothing, but that's not so - you have the local copy on your hard drive, and presumably you can open it in FP 2000 can't you? You don't need to uninstall WSFTP, and you shouldn't start moving files and/or directories in your existing web - you'll get in a mess if you do. Just leave things as they are, and we'll see if we can sort out the problem. Answer these questions carefully if you would:-
1. Have you at any time published the whole of the site to a server?
2. If so, does the server have FrontPage extensions installed?
3. Do you have a safe copy of the site - as it stands - on your hard drive?
4. Can you open the local (hard drive) copy of your site in FrontPage?
Come back with those answers and we'll go from there.
