my POD is not giving any output to my pc or amp.

all i'm getting is a high alternating beep

It's used so is something broken or is my stupid face just too stupid to understand this thing?

Did you plug anything else into any audio inputs on your computer? I've had similar problems with my ME pedal when I had other audio input jacks in use and was trying to record through my pedal.
