Someone please help me out here. I bought a NE410 yesterday. I have not been able to transfer any songs to this thing. MP3s I am transferring are 128kbps or above. When I use Net MD Simple Burner to rip songs from CD, it fails half-way through saying "The Reading session has stopped." When I try to transfer MP3s using SonicStage, I get "An error occurred while converting the data." Then something about SonicStage System Information Restore Tool comes up and asks me to connect to the internet so that it can verify my database. When I try to transfer MP3s using RealOne, it tells me that there is not enough disk space. I'm using a brand new MD disk with no information on it. I have already uninstalled and reinstalled this software like three times. Please help me here. I have WinXP Pro, 512MB DDR, 40GB hard-drive (if any of these is relevant). Thank you in advance!
