The EPS files exported from Maple 16/17 cannot be read into Word 2010. This seems to be a problem with the import filter of Word, which oviously tries to interpret the postscript code, while older filters just embedded the EPS file.
One workaround is to import the EPS file first into Corel Draw and then export again as EPS from Corel Draw. Corel Draw also interprets the postscript code and creates a new EPS file which is compatible with Word. Probably by not using some Postscript Level 3 features which maple uses - not sure. Unfortunately Maple exports text as curves, so that text is not editable in Corel Draw.
However, this procedure gives you the high quality (scalable vector graphics) that you probably want.
There might be other tools which can import, interpret and export postscript files.
