Here are some tips that may make your streaming experience better:

1. If possible make sure the computer you are using is plugged directly into the network.
2. If the live stream has stopped playing try refreshing your internet browser.
3. Make sure you are not downloading large files or streaming other videos during the live streaming session. It may take away bandwidth that would allow a better viewing experience.
4. Before you are able to participate in the chat feature you must be signed in with your YouTube/Google account. Sign-up is free if you do not have one.
5. Please be patient with the live stream host. This is a live production and just like being at a physical presentation, problems can arise.
