Edit page not working in Contribute

I have a site that I administer in Contribute, a user called today because they are not able to Edit a page. When you click the Edit button it just sits there. As the Administrator I try to go into the file and I can't get into it either. I even recreated the page in Dreamweaver and it is still hanging.

I looked on the site and there is not a .lck on this file.

Thank you in advance for any assistance.
