I've been designing a website for my mom and I had uploaded it several times and it worked great. I was nearing the completion of it, but I added a few more pages, and all the sudden it wouldn't upload anymore! I keep getting the error message "Program could not create a catalog". I checked the folder of the website to make sure all of the files were there, and I can't find the files for the pages that won't come up in my preview. I've searched my whole computer for them, and they appear to be non-existent, but they show up in VSD, just not in the preview.

Whatever advice I could get to fix this problem would be MUCH appreciated!
Thanks!
