Publishing Microsoft HTML Help

Hi,

I inherited a very large FrameMaker document that was originally created in FrameMaker 9. The person had a complex (and ridiculous) system of importing the Frame book into Madcap Flare to generate the Help File (and it usually took 3 to 4 tries to make it work).

I purchased FrameMaker 2015 so that I could publish the Help file straight from FrameMaker. However, it has been 6 weeks and I still haven't successfully managed to publish.

The Book consists of about 20 chapters. There were thousands of cross-references, several conditional Tags, and quiet a few variables. When I attenpt to publish, it will get a few chapters deep, then it just hangs.

If I remove all the files from the book and attempt to publish a few files at a time, I'm successful. However, there are a few files that still won't publish, even on their own. The pop-up appears and says it is converting, but it goes on forever.

I originally thought it might be an issue with the number of cross-references or conditions, so I removed EVERYTHING from the document. But no matter what I do, there are a few files that simply will not publish and I am forced to force quit FrameMaker each and every time.

I've scoured the internet to determine the cause, but I'm stumped. Is there something obvious that I must be doing wrong?

Thanks.
