if it doesnt work, i tried this method. it may not work for you, depending on your computer (the settings)
right click + save target as...
once its finished downloading, right click on the icon (pmorebrighter, pmoremyheart, or pmorenltg) and go down to properties. find this:
Type Of File: MP4 file
Opens With: Unknown
right there where it says 'Unknown' next to it it should say Change... or Open With... A window will pop up and you should choose Quicktime player if you have it. thats the one i chose.. you can try windows media player but im not sure if it works. recommended one would be Quicktime player tell me if everything goes alright, if not ill try to find another way
