I have about 15 hours invested into this video and right towards the last 30 mins of editing I experienced a scenario where my files on the video timeline were going blank and white on the screen as I passed my mouse over. I clearly wasn't able to continue to edit, so I saved the file and then closed the software. Upon reopening my WMLP file, it was confirmed that I lost everything as this was the screen shown to me (see picture attached)
