I currently downloaded an mp3 file but could not play the file. The error message I saw was, "can't open the file because it is either not signed with a trusted certificate, or one of its components cannot be found. If the problem exits, try reinstalling or restoring the file"
I usually play my video and audio files with the preinstalled windows media player from my phone.
I have also realized that, all my audio files have similar problem - the do not have their extensions like "love.mp3" or "LB.wav" but they rather look like a windows logo icon.
how do I solve this. Thanks
