I am having problems with the 10.1 Mathematica Arduino device .

arduino = DeviceOpen["Arduino", "COM3"];
DeviceConfigure[arduino, "Upload"];

DeviceOpen::noclass: A driver for Arduino was not found on your local computer or currently available paclet sites. If you can locate the driver, add the driver directory to $Path or load the driver directly with Get. If you cannot locate the driver, contact the device manufacturer or create a driver using the Wolfram Device Framework. See http://devices.wolfram.com for more information. >>

DeviceConfigure::ncdev: $Failed is not open. >>

This problem started this morning for no reason. Any help?
