Installing asio4all - cannot find advanced button on opening flock

I have installed asio4all by following the video. When I get to opening flock my opening page has no advanced button on either member or leader setting. On the page I do get ASIO is not an option in either dropdown menu for microphone or speaker

Sorry about that… the video is based on an older version of Flock.

Click the Settings button and then at the top of the page click where it says Audio
