Joe from KJWHF Amusements in WA (The Stern distributor), sent me a new SD memory card, with a fresh install of 1.05. The music and sound issue has disappeared and my game plays perfectly.

Someone else mentioned they had similar issues ? PM me and I'll forward on a second card Joe kindly sent me.

It IS a known issue with the SD cards, and in some cases, may be undetected for a while and become intermittent. Mine did it all the time.

  for Joe at KJWHF - who's after sales service is second to none.
