My video preview is not working all of a sudden. I was away for three weeks (my pc was shut off). When I returned, if I load any video items in the timeline (including loading projects I edited previously) the video preview window show nothing (either a black screen of just shows the window behind it). If I open a new project any video or picture I put on the timeline has the same symptom.
I am on version 14.0 build 252.
Thanks
