[15:15:09] UDP packets cannot be sent to or received from the server. Switching to TCP mode.
That one sounds like a firewall problem on your side. Either a software firewall on your computer, or the firewall in your router. But the TCP mode should work anyway.
The privileges one is strange. Did you create a certificate when it asked you to during the initial configuration? Also it seems like you managed to join, so try registering yourself with the server (right click your name and click "register yourself"), this might fix some of the permissions trouble. Though I've seen it cause different trouble.
And the chrome thing: strange. Really strange. Only explanation I could imagine is that it's the TCP mode, but I don't really know how.
By the way: I can't join you right now, as I'm on my notebook, without a microphone, and I need to go to bed now.
