I have lost the use of the youtube on the skybox f3 as worked for a good 12 months then all of a sudden it as stopped working.It will load up but when i select a video to watch the circle thing goes round then stops again it just won't load videos up.Anyone else having this problem or offer any advice on how to fix it

I have never updated the firmware on this since last year as it's just the box in the bedroom,anyone link me to an update in case this is the reason
