Hey @Tony Race Graham, you know, admitting to pirating something and apologizing is a good thing to do. I hope you can get away from pirating entirely (if you do more). AND you decided to leave it for a legitimately free option, so good for you!
I'm glad you enjoyed the video, I hope you enjoy Cakewalk too.
As for your mic, you would need to go into the preferences menu > Audio > Playback & recording and set your Driver Mode to MME (32-bit), which should support your USB mic. If not, try the other ones, they may work and it will tell you if it's not supported.
Then, go to the playlist and make an audio track. Go to the input options (the option below "Clips") and to MME Devices. Select whether you want MONO or Stereo and then press the record button on the track, then when you're ready, press the main record button on the transport bar on the top of the DAW.
