Space Station 13

Sorry, I don't know if this is where I should post this, but here it is.

So, I have Byond downloaded and working, but when I try to join a server for Space Station 13, all that happens is a white window opens saying," BYOND: Your Game Is Starting" and nothing happens after that.

Am I doing something wrong, or did I miss a download or something?

Here is a link to what I am seeing.

(BTW, I'm on Windows 8.1)

Thanks for anyone that could help.
