I cant watch the videos on the mages update.

http://na.leagueoflegends.com/en/featured/mid-season-magic on this lol link talking about the MYMU and dragons, You're suppose to be able to click on the champion and see their new passives and updated abilities like in champion spot lights. But every time I try to open it and watch the videos my screen freezes and I have to close the window. Is any one else having this problem? Or are you guys able to watch the videos?
