Well, either downgrade the emplode or upgrade the player - of course, the later is recommended

You will need serial connection to upgrade the player if it is still 1.03 or any HiJack-less version (newer versions with HiJack are upgradeable over the Ethernet). Concensus seems to be 2.0 final with the most recent HiJack, and both emplode and jEmplode will come handy.
