Laptop won't recognise my Start 25 any more. It appears with an exclamation mark in Devices and Printers. Also the driver appears with an exclamation mark in Device Manager. In the details of the driver it's said that it "This device is not configured correctly. (Code 1)". I'm invited to update it. I uninstall, re-download MyDriveConnect. Same thing happens. I've tested the USB ports and they're fine, and the USB drivers are up-to-date. This has happened many times. I've done the soft re-set of the device, too. But today, a new thing: when I re-download MyDriveConnect, it's stopped even downloading the faulty driver: it doesn't appear in the list in Device Manager any more, and instead of being told that the driver has not installed properly, I'm told that "TomTom has no driver." Ready to give up. Any ideas gratefully received.
