I assume that you did try the Design Checker tool, and that did not find any
problems on that page? If it finds issues on that problem page, see if it
can be corrected from there. If it does find issues that can't be fixed,
note them and post back after trying the next two steps.

The next thing I would try would be based on the assumption that you have a
corrupt image on that page. Back up your Pub file, and then go to tools >
graphic manager. Find the problem page, and replace all the pictures with a
small 100 pixel wide, or at least a very low resolution .jpg or .gif image.
In the graphics manager under Select a picture, click on a picture file on
the problem page, and click the downward chevron to see your options. Choose
replace this picture, and browse to your small low res picture. Replace all
the images on the that page, save and close your file. Open it again, and
see if you can click on your problem page without crashing Publisher. If so,
you know that the problem was with one of your pictures and you can rebuild
the page accordingly. Just add back pictures one at a time, saving, closing,
re-opening and testing after each image is added. When it crashes, you found
the guilty party.

If replacing the images doesn't work, you might have to just delete all the
pictures on the page. Just select the pictures, one at a time, on that
problem page under the graphic manager, and hit the delete key. This will
delete the images off the page, not just replace them. It will be harder to
rebuild your page as you will have to insert new images and graphics and
size the boxes, but it might be necessary to open that page in Publisher.

Try those three things, and if that doesn't work, report back as to what
happened, and we will try something else. It would be a pain to copy and
paste 49 pages of a 50 page file into another instance of Publisher.
