Why have my thumbnails disappeared since my Solidworks upgrade?

Hi there,

I have solidworks student edition and I have done since 2013-2014 but since my latest upgrade to 2015-2016 my saved files no longer have small images or my part/assembly which was really useful to find the file I needed as I have many files with very similar names and it can now take a lot of time trying to find the file I need.

Does anyone have any ideas how to get it back to images of the part/assembly rather than solidwork's own part/assembly thumbnail?
