Can't pull clips into storyboard

[Greg]

My son created a storyboard in Video Maker. Somehow,
he's done something so that all the clips in the
storyboard now show up as red X's. If I right click on
these clips and look at Properties, I find that they have
filenames and are located in the Collections area of the
application. But the software for some reason no longer
can pull the clips into the storyboard.

My son may have inadvertently deleted a handful of clips
that were part of the storyboard, but the majority of the
clips can be found in Collections.

It seems the program is not able connect the storyboard
filenames with their actual location.

I don't know what to do.

Help!!

The clips in the project file must be connected or linked to the source
files on the computer. Once into the timeline/storyboard, they are not
related to the clip info in the collections.
