When I browse to a Zoom Gallery photo page on my site, I get the following error:

www.hamiltoncountytoday.com/index.php?option=com_zoom&Itemid=36&page=view&catid=17&PageNo=2&key=9&hit=1

Not Found
The requested URL /index.php?option=com_zoom&Itemid=36&page=view&catid=17&PageNo=2&key=9&hit=1 was not found on this server.

Apache Server at www.hamiltoncountytoday.com Port 80

The site was working fine for the last month or so and suddenly started giving this error message on Monday. I haven't made any back end changes to the site in the last week or two. I did migrate the site to a new server but that was two weeks ago and it's worked fine since then until yesterday. Anyone have any ideas as to what might cause the above error?

Here's my setup:

Zoom 2.5.1 RC3 (Using older version for compatibility with CB)
Zoom CB Plug-in
Community Builder 1.1
Joomla 1.0.13
mod_zoom_pics
