How can I edit a website I uploaded?

I uploaded a website I create using Microsoft Expression Web 4. After uploading it, I find that I cannot edit it in Website Builder. Is it even possible or do I need to rebuild the website using Website Builder?

If you build a site using another builder or software, you cannot edit in in Zyro website builder because the files will not be recognized. If you want to edit your site content, you need to edit it in Expression and reupload it.
