I had this happen too after I migrated to my new Mac. To fix it, go to Store>Turn Off iTunes Match. Then turn Store > Turn On iTunes Match and/or Genius and things should start working again.

Perfect - thanks so much!


For anyone else wondering, the clue was in what was displayed on the screen after I turned iTunes Match on again: it asked whether I wanted to add this computer. Having copied my iTunes library over from the old machine, I'd completely forgotten that iTunes Match identifies each computer uniquely (not each iTunes Library), so was never going to work with this one until I specifically added it. Sorted!
