Standard advice in this situation is to save two copies of the document and trash one half of the content from one copy and the other half in the second copy.
Then try to import into a test project to see which half chokes. Repeat until you find the cause.

Thanks for your reply. I tried a small section, maybe 3 pages, but the
images didn't come in. Now I'm cutting and pasting from Word into RH topics,
the text first, then import the images later. Seems to work well, but a
little tedious. Then I'll build the books and ToC after all the text
and topics are pasted in.
Also, Peter, what do you mean by "trash" one half of the content? Do you
mean just cut the document in two, save copies of the original and try to
import half the document? And do you also mean the images contained or just
the text and add the images later? Thanks, Gloria
