Just built a new PC and installed fresh Windows and Movie Studio copies.
Noticed that thumbnails of particular video files were not loading, and after installing K-Lite, that issue resolved. But those same videos still won't load in Movie Studio 17, with an error message reading "The Application does not support this file type."
On my last PC, these same files did not have such an issue. And on my tablet, I'm still able to load them into Movie Studio 16 (though both my tablet and old PC are/were too slow to be able to efficiently edit them)
Tried uninstalling/reinstalling to no avail.
Any advice?
