403 Error

I am having difficulty with my website. I uploaded the files to our site a few months ago after a few tries and have recently had to update/change some pages. I use Publisher to create the pages and them publish them to the web by copying the web pages to my computer and then using SmartFTP to transfer the files to the site. This time it is not working. I was able to remove pages to my site that I didn't want up there anymore, but I haven't been able to post the new pages. The more I try to fix it the worse it gets. The files appear to be OK in the SmartFTP window, but when I try to go to my website to see how it looks, I now get an error 403 that says I need to log in to open the site. I have never had this happen before. Can you help me?

Yeah! I'm up and running again.
