installed on your server space DO NOT try to upload files via FTP - unless you (or your web host) first disables the FP extensions.
You say in your original post that you've 'bought a server' - is this really the case, or have you rented some space on a web-hosting server? If you have your own server hosted by someone else you'll be the one doing the server-side configuration, and our advice may be different, so let us know what you have.
It's possible to import a DreamWeaver site into FrontPage (and vice versa) and then you can publish in the normal way. If you've built the site in DreamWeaver there won't be any of the special FrontPage components in it, and you won't need FP server extensions anyway.
It's all a little confused, so let us know exactly what the position is,and one of us will respond.
