Malformed topic error - RoboHelp 9

Hi,

After checking out every suggestion on dealing with this error with no luck (including Peter Grainge's print issues and every other posting on malformed topics), I am at a loss - any help/suggestions on a solution would be GREATLY appreciated.

I have three single source print layouts in my project - Administration Guide, Operations Guide, and Reference Guide.  A few of the topics are common to several of these layouts.  WebHelp compiles perfectly along with all three different TOCs.

The Administration Guide generates a printed document, which needs the usual formatting in Word, but all the topics generate.  When I attempt to generate either the Operations or Reference Guide I get the malformed topic error message after about 10 topics - not always on the same topic.  Here's the puzzling thing to me - the topics that hang are topics that generated just fine in the Administration Guide.  Is this perhaps something to with my conditional build tags and the same topics being used for multiple layouts?

Print Wizard settings:

Generate Word doc only.

Location -different folder for each single sourced print Guide

Conditional Build Expression = None

I have tried using the Microsoft Word Template styles and the Stylesheet - default.css in turn with the same result.

I have been scouring the html code for weird leftovers from cutting and pasting topics from a previous Word doc (This project originated in Doc-To-Help, but as I had not created online Help previously, just a pdf output, I started a new project in RoboHelp and created each topic from scratch, but did cut and paste text from the Word doc.  I thought perhaps there might be an issue with Word tables which are plentiful in this project, but the error starts with topics that have no tables in them.

Any suggestions, thoughts VERY WELCOME

Many thanks in advance,

Sally
