Ya, when hitting that nothing happens. It's all set in settings but nothing happens. 

We're all set. 

i'm having trouble finding the adobe flash  options to change the microphone setting.  I still have to hit Allow and sometimes it seems to freeze.

I always have that trouble too. Here is a paste from the Rocket Languages help section:

I keep being asked to "Allow"
Please right click on the ROCKET record heading and select Settings. In the privacy tab, make sure "allow" and "remember" are ticked so you don't need to repeat this process.

Hope this helps.
