Beatsource LINK won't play if USB tracks loaded

Just signed up to the Beatport link trial. Logged in on my SC5000’s, started to stream tracks (superb feature btw). Ran into an issue:

  1. Select a USB drive to load and play a track on either of my 2 SC5000’s
  2. Change source to Beatport LINK, load a track (‘Downloading’ message appears). Track isn’t loaded into the player. The previous USB track is still there.

Firmware 1.5.2

Have I missed a setting or something?

Update: left decks untouched for a couple of hours, went back and beatport started working again. Wtaf
