I myself always make a copy of a file before modifications, for example if
my file is "site.pub", I'll copy it as "site_bku1.pub". Certainly that
should be done before a version change. For example I would have saved off a
copy as "site_bku_ver2000.pub", before converting the file to 2003. If a
file is important enough to retain then it's important enough to take common
sense measures to protect it's integrity.

Can you open the file in 2000?
Can you repro the issues in 2000?
Or is this specific to 2003?

Are you running Norton AV ? If yes you need to visit their support site for
all the fixes you need in order to use MS Office. Norton AV is proven to
corrupt Publisher files. Of course backup copies in this event would be
useless as a copy of a corrupt file is itself corrupted.

My strong guess is that, yes you are running Norton AV. And that Norton
corrupted your file. Personally I despise Norton products. My AV
recommendation is mentioned on www.davidbartosik.com . It was during Pub
version 2002 that MS verified that Norton was corrupting their files.
Because customer files were crashing Pub 2002 all the time. As a result of
this MS made modifications in the 2003 release they dubbed "bullet
proofing". In a nutshell what that means is that Pub 2003 should open the
corrupted file without crashing itself, but, it probably will not be able to
modify the file.

Basically a corrupt file is just that. If you can at least open it and
browse it without crashing then you can open another Publisher window and
cut and paste the pages over into a new publication file.

Fyi, in the area of web design Publisher 2003 has very significant changes
from 2000. Most of which took place in the 2002 version. So that you aren't
back here with tons of questions I'd highly recommend you find out what you
are in for first. Visit www.publishermvps.com and visit the web design 2002
section and 2003 section for articles I have dealing with version changes.
You would also want to review the web design FAQ page.

I see that you did upload this as a 2003 web. But I can tell from the code
you uploaded it in the manner that I strongly recommend you not do. Do not
publish the web using File, Save as, web page. Doing so will use a code base
that was introduced in version 2002, created endless grief, and got pushed
from the fore front in 2003. You want to use File, Publish as web.
