Disconnect the player from the pc, browse to the adfu inf file, rightclick and choose install. Restart the computer with the player attached, and see what gives.
I have the same problem with my LG fm37 4Gb. The PC restarts everytime; I'm using XP SP3. Is there some other driver or something??? My player is stuck in rebuilding library screen after I have uploaded a huge video file on it (2Gb) by a mistake. Need help!!!
Have you tried a different USB cable to see if that helps? I wonder if a faulty USB cable is causing the crashing problem as it's not getting detected properly.......
