Toon boom aren't importing videos!

I tried to import a video and I cannot do this, when I import the video nothing appears on the screen and the screen is the normal way but it was to appear the video and it does not appear! The video is in .mov format. Can someone help me?

You need to have Quicktime installed.
Unfortunately the latest versions of Quicktime
( 7.7.7 and 7.7.8 ) are broken on Windows 10 so
you would need to install an older version.

I’ve been having the same issue! When I open the ‘Choose a file’, and click & open the video, the GUI to select a layer doesn’t show up,I’ve tried restarting toon boom & my computer, but nothing seems to work! Help? >:(
