Hi, I have a problem and I hope you can help me figure it out. All of a sudden I can't drag and drop songs from my pc to my mp3 player (regular panasonic mp3 player) I can do it if I use windows media player but if I try to do it manally like I used to, I can't. The same with my digital camera. If I connect my camera to the pc using the usb cable I wont be able to read or write or do anything. I will have to take the sd card out of the camera and stick it into the computer to actually manage the pictures. I've tried everything, from uninstalling the usb controllers to connect the mp3 player to all my usb ports and nothing works. If iI try to drag an mp3 file from the hard drive to the mp3 player I'll get this message: "The device has either stopped responding or has been disconnected" And if I try to drag a file from the mp3 player to the hard drive nothing will happen, I'm able to see all the files in the mp3 player but wont be able to copy them, yet, I can delete them... Anybody??? Thanks in advance
