FMS URL >?

I have been working for hours, studying and trying to get this software to work with just a simple audio file. I am just trying to use it to stream a live audio signal to  another PC in another site to feed into an FM transmitter. I am new to all this but cannot get the correct settings in the FMS URL . I don't know whether to enter my IP address of the PC that I am speaking into to stream or what it says  or what . I have tried numerous settings but will not connect. Just what exactly do I put here so that another PC can access the audio file that is streamed ? I cannot figure it out. also, is there any other settings that I need to change to start streaming a signal to others ? I always get error Problem with primary server .  thanks
