PowerShot-x

I have this mp3 player Sony NW-A3000, and have used the software Connect player. But thats a while back in time I used the program, or entered some music in to my mp3 player. So I'm back to use it, but I see that there is an new software program for the player, and that atraclife forum is closed, and if I understand right that the atrac format is closed to, or not in use anymore. Can someone tell me something about what hapend. And are am abel to use my NW-A3000 mp3 player anymore. I feel litle lost, because it's so long time since I used the software, and the player.
