able to view all the videos but one

I can view all other videos but I just can’t view the ACCA F7 TRANSFER OF NON-CURRENT ASSETS under chapter 8. I’ve tried it for two days with different devices and different browsers.I’ve used different computers and smart phones but still can’t view this video. It gives me the same thing, it is blank no buttons or whatsoever…I can see the comments under the video but there is nothing on the top where the video supposed to be except the big red title. HELP! Can anybody please help me out here!!!!!!!
