Playback cuts in and out for some reason

Hey so,
I just started using Cubase and for some reason the playback with my vocal tracks, recorded with a Nessie Blue microphone, cut in and out so I can only hear parts of the recorded vocals at a time. This seems to happen with every vocal track I try to record and I honestly have no idea why.
Any guesses, and has anybody experienced this before??
I could really use some help, thank you-

Are these gaps showing up in the waveform? Then we know whether it’s a playback or recording problem.
