Can't watch Game Of Thrones, video is crashing


It’s the third episode already, the first didn’t run at all so I had to watch it on VLC, without subtitles, the second and third ones worked till 1:29 when the “previously on the game of thrones” scene ended and the intro song was about to come in. It says “video reproduction had an issue. Please try using another program such as VLC to watch this content.” the deal is, when I play it on VLC, I dont know how to put on the subtitles, can anyone help me?
