Problem publishing pages in Contribute

[tamhise]

I use Dreamweaver and Contribute. I have never had a problem switching back and
forth. I use Contribute of course just for content management. Anyway, I went
to publish a page in Contribute yesterday and got the message "To avoid broken
links on this page, Contribute needs to publish the following new pages:" and
then it has a a bunch of pages listed which are not new pages. They are pages
that have been there all along. With the filename of one selected and I hit
publish it then says, "The filename you entered already exists. Please enter a
different filename." I don't want to change the filenames of all of these
existing pages. That would then mess me up in Dreamweaver. I don't have any
problems in Dreamweaver right now, but I'm wondering if something I did in
Dreamweaver has caused this. This same day I was in Contribute it also said
that all my hover.gif and nav.gif said they were not there, but they are. They
show up in the picture and they are there in Dreamweaver. I am using the
Studio8 CS2 versions of Contribute and Dreamweaver. Any help or ideas would be
great. Would it be best to start all over with contribute and pull in the
website again???? Thanks.
