Why is there no image of mobile lily to watch live broadcast?

I am a Guangdong user, because I can't find the Guangdong version of Lily, which is used to non -Guangdong version. I installed it once before, I could watch the live broadcast, but I thought it would be deleted. Later, I installed it again, but when I watched the live video, there was no image. The screen was dark and black, only the sound!
