option enabled in File -> Preferences.
Incorrect port selected. Select a port from tools -> port menu; it's got COM4 selected (which presumably you used previously), but it's saying that there is no COM4. Windows will often assign a different port number depending on which USB port a device is plugged into (and occasionally for no apparent reason), so you just need to select the correct port.
