Then you didn't have the latest firmware on your player previously.
So:
1: Download the latest firmware that's exactly for your version of the player (T for TP, S for SP and SL versions, 2004.6 currently for all 3. Do not switch up the versions or you're in for a DFU Tools learning course.)
2: Extract the downloaded file into the root folder of your player. You should have an M6.EBN file (M6SL.EBN for SL players) and the resource.bin on your player.
3: Unplug your player.
4: Switch your player off, then on. You should see an updating firmware, then a flash, then it turns off.
5: Turn the player on again. You should see updating resources
6: Enjoy
