Error displaying videos or power point


I have a problem displaying in preview the power point and videos files.

The log shows me the next message (for a mp4 file):
unlink(D:\LIBRARY\temp/20160116.mp4): No such file or directory

Thank you.

is it the same on display device?

It will have something to do with either your proxy settings or incorrect CMS library path in CMS settings. (it needs to be fully qualified path)

I checked the path and I changed the uppercase to lowercase for everything.
Then, the preview shows me nothing, not even the text, just the “Play again?”.
So I changed again the duration for the video from “0” to “240”, but shows me nothing on preview (just the text and the background, not “Play again?”) and nothing on log :anguished:
