URL and access date wont appear in Chicago 15th! HELP

I think you are saying that the link is hyperlinked in the bibliography, but not in the footnote.  Is that right?  I can’t help on this occassion.  I rarely use footnotes.  - but that is what happens to me in a quick test.  I suspect it is something to do with fields in footnotes and how Word handles those.  Tech support or a user more familiar with Endnote and footnotes might be able to tell you more.
