I have just reinstalled MyDrive on a Windows 10 laptop but the TomTom is displaying an error screen which indicates that the device is not connected to the laptop. I have tried several USB ports and a different cable but with the same result. I've tried disconnecting and switching off and on - same result. I get the TomTom start noise, then the loading icon, then the error screen. The laptop says it's downloading updates, then that the device isn't connected. Sometimes it says the server is busy. WTF?
