I don't work on Windows for any Blackmagic-related operations at all but my suggestion would be that instead of merely selecting "update" for Media Express, delete all of the BM Desktop Video package components completely (use Blackmagic's own Uninstaller but perhaps even third-party applications). Having done so and rebooted, then do a clean install of everything.
I'm not not offering it as a guaranteed solution by any means but I've found that for BM's Desktop Video driver set it's the most effective method.
Blackmagic Teranex 2D, Ultrastudio Express, Intensity Shuttle (Thunderbolt), Two H.264 Pro Recorders (Mac OSX) & lots of old VTRs used for digital archiving of legacy video formats for major libraries, broadcasters, universities and public archives.
