I was playing Just Dance 2014 the other day and I've saved some videos and the save process went well. Few days later I wanted to watch them and they were all gone. I decided to record one to check if it works and this is how it looks like: I save my video, the save process finishes correctly, after that the share button is still inactive, and when I continue and try to play the video it is gone. I've checked in the same song menu (Just Dance tv button is inactive) and in the Just Dance tv menu in my channel section all the boxes are empty. Also when I go to Just dance tv section the video in the middle is playing with some funny guys dancing, and it is changing for the next one after that, but when I enter any sub menu like most viewed, featured or most recent (or my channel) the boxes are empty.
My internet connection is good, and I am connected to the PSN all the time, other online features work perfectly and I was playing for hours on the world dance floor.
I've already registered a ticket in the support section but they sent me here to the forums.
