Also having this same problem on my stream. I also noticed none of the videos are staying on the "Latest Videos" section. A local file is saved in my My Videos folder, but none of my recent streams save on livestream.com.
My last video is from last Thursday. On Monday we did some stuff in Minecraft which I set to stream, but never actually looked at the stream on livestream.com. Said stream is not saved in the latest videos area. However, I have a local file of it.
Anyone heard any solutions yet?
