Cinema Experience Add-on problem

Hi, I just installed OSMC in RP 2 B, and installed Cinema Experience Add-on. I see add-on icon and settings. I try to play itro trailer/clips before every movie. It is not running at all. I selected some mp4 file as this trailer. I keep such file on SDCard where OSMC installed and boot, in the root subfolder /Videos. Cinema Experience settings saves this file and displays as it selected correctly. I selected all add-on Home controls to be trigger.

No trailer plays before any movie I started. Any suggestions?

I checked the selected trailer file, it is playing very well alone.
