Mic isnt detected or recording

Recently purchased an at2020 microphone and ART Tube pre-amp for my windows xp pc. All set up correctly but audacity isnt recording anything or detecting sound on the monitors. However when i press record the left and right playback stereo’s have a little bit of green meter in, and the left recording stereo monitor has a bit of red in. I dont know what to do, i have tried choosing different preferences and microphone options but still nothing. Please Help! Cheers…

You missed the important part of the description. How did you connect the Art preamp to the computer?
