New installation; started downloading saved emails, but stopped before finished

Hi, I have just installed eM client and configured it to my hotmail address. It started downloading all of my emails that are stored on my hotmail account, but stopped downloading emails from November last year.  The thing is, whenever I get a new email, it downloads it no problem, but it won’t download all of the emails from November 2015 to yesterday.  I have tried clicking on the send/receive button several times, but it still refuses to download the missing emails. Any help would be much appreciated.
