If problems between MS Word and FrameMaker persist, consider removing all graphics before conversion. Reimport them later by reference.
Consider converting tables in Word to tab-delimited text before importing them into FrameMaker. Convert them back to a table after the import.
Consider getting rid of headers, footers, table of contents, and index, from Word before importing into FrameMaker--although the TOC and index might come in fine if the planets are aligned in your favor.
The FrameMaker MS Word and RTF import filters take a looooong time. This time gets especially long if you have some complexities in the source file. Often, Windows inaccurately reports the program as "not responding" when, in fact, the import is still on going. Give the filter a chance, an hour or so. Make a five-course lunch or otherwise occupy yourself, just to give the import filter a chance.
