Hidizs AP100 Problem

UPDATE: After the new firmware 070, now my problems gone! Thanks Hidizs for support. ============================================ I had an issue with the card especially with 64gb card, while playing music it start to crazy rebooting by itself. Tried to reformat the card to Fat32 or NTFS with 3rd party software didn't work at all, tried with another card (in case i only have 1Gb card) seems work for a moment but the problem happened again. And this morning i was shocked because i tried with no card and i got new problem, the device turn on by itself after i turned it off for about 25s. Anyone had same problem with me? How to fixed it?
