I recently downloaded Lightroom 6 for a trial and built a slideshow with photos, videos and music (about 1.7g). I successfully exported it as a video (however, it took over 24 hours!). I then upgraded to Windows 10 from Windows 7 and built another slideshow (about 1g). When I try to export it as a video, it gets part way through then quits. The Microsoft message is that the program stopped working correctly so Windows shut it down. In addition, they say there is no current fix for it. Any one else encounter this? Any solutions to recommend? Thanks.
