Over the weekend my 30gb unit took a turn for the worse. After playing for about an hour (in home), it began to distort the song that was playing to a point it was just noise and then completely locked up. Powered down a number of times and powered back up but could never get pass the boot logo, no buttons work, nothing. Came into work today to try to unlock it by changing the v2.0 beta11 software back to v1.03 and came up with this error during the "upgrade"; bad pump response error 0x25. This came after about a 10 minute wait while the upgrade window said "selecting pump device". Any ideas on this??? Currently the player is stilll locked up at the boot screen. Thanks
