So after far too many hours of being told by my pc that I had bad drivers and adb not showing the device I finally got it working. I had deleted my android directory and reinstalled it with the easyadb installer with driver. That alone didn't help until I went into the nook's settings and disabled/reenabled the USB debugging feature. Now I can easily reconnect by disabling/reenabling the debug feature. This was done in win 7 x64. I hope this can help others.
