Help Needed by Microphone

    Okay I finally get a microphone tonight so I can start
    scanning books and recording myself reading them to show
    on my Smartboard. Well I plugged in the microphone and
    clicked the button that said configure and NOW the sound
    on my computer won't work - Just fuzzy sounds! Help
    before my husband finds out!!! What can I do to fix this
    problem? Thanks!
