Hi
I noticed that the link to your gallery page returns an error - which is most probably due to the word gallery being misspelled in the link:
http://suereinkekitchensandbaths.com/galery.html
I'm not sure about the 'unexpected file format' problem - sorry!
Do you have a special folder on your harddrive for the website? I wasn't sure why you were looking in the backup files folder for your pages.
(I think it would also be a good idea not to have new pages opening. When you click on a link to edit it, you can delete whatever you have under 'target' - you probably have '_blank' there.)
I agree with Ann that your site has a nice presentation.
Best of luck with everything!
