I know it's little consolation now, but I'd never advise building a site online, especially if it's non-trivial. If it's important enough to matter, you should really learn to to do your own HTML and graphics, keep it all on your PC, back it up, together with all your other important documents which I hope you back up regularly (?) and upload the web pages to the provider's site.

One advantage of that, which I have found useful several times now, is that you can move the whole site to another provider quite easily. In this case that sounds like it might be advisable anyway.
