Hi yguerrero2010,
Sorry that you have to experience that.
I checked, and I got sound and video. See image. Would you mind checking a different browser, or restarting the one you have used, perhaps clearing the cache?
Fingers crossed, this problem will not bother you any longer.
Since you asked in the Tutorial Forum, I can’t move this post to the Cineversity Site Problems Forum; Otherwise, future questions to this tutorial will go there as well. But if your problem continues, please use this forum. Thanks in advance for your patience!
All the best
