Won't Record with New Microphone

I downloaded audacity onto my new computer and did a test drive and it worked fine. However, I tried to use the blue snowball microphone and it won’t record. I hit the button and it looks sort of like its working (like, you can’t hit the buttons that aren’t stop) but the line doesn’t move and the sound doesn’t show up. It still works with the computer’s built in microphone, just not with the one I want. How do I fix that?
