WD My Nook Elite 2TB wont show up in windows

Well this is my second My book I had to send the first one back to the place I got it since the ports on that back were really hard to get the usb and power cables in, this one is a little better. Now when I plug this one into the computer it wont show up it did the first time I hooked it up then tryed to copy a few movies on it and it gave me an error. Now when I plug it in I get nothing at all. I have gone to Device Manger to see if its there and it says USB mass storage Device with a ! on it.  The status on it says This device cannot start. (Code 10) any idea how to fix this??

Edit* Nevermind I got it working I uninstalled my printer and it works :confused: weird.
