X3 Project Stops Building - Help!

Question

I'm back working in X3 - and it has been a few years. I have
been tasked with updating a help system created by another author
(and, of course I'm on a short deadline). When I try to build the
HTML project, Robo APPEARS to be building and tells me it has
completed, but the .CHM ends up being an empty file.
I'm getting the following warnings that will probably be
ridiculously easy for others, but I'm not catching the problem.
HHC3003: Warning:
setup_main.htm :
The HTML tag "td" has invalid characters appearing before the
closing angle bracket: ;
style="width:62px;" width="62px" class="hcp3"
She created a template to develop each page so this error
appears on several pages.
I'd appreciate any insight!
In addition to the error I mentioned before, I'm also
noticing the following behavior. I have recreated the project from
scratch twice, imported the topics, and was able to add a TOC and
still have the project continue building (including these files
with the "td" error). But each time when I tried to add an Index,
the project stopped building.
Are there service packs I'm missing? Could I have something
set wrong in the project?
I really appreciate any help that anyone can provide!
Thanks.
Liz

Ok well as I said I have not been using the software for long so I do not know if this was an easy fix or not, so I wasn't sure if all that information would be relevant, so forgive me. Here is the information you might need:
