tomtom updates

The TomTom help line was not available over the weekend. What puzzles me is I didn't do any of things mentioned above recommended by TomTom except turn the sleep mode off and it finally updated. Or at least the "no maps found" has gone away and I have a map. I did plan a trip and it shows the route. The TomTom icon at the bottom right of the screen will now allow me to click 'settings' and I see where you can clear the 'cache'. I didn't do this as WoodGlue suggested over the weekend because it didn't seem to work. I right clicked and left clicked and cursed to no avail. Settings was not highlighted or available. I have myTomTom on desktop (newer PC) and on a laptop. The laptop goes on trips. I used the desktop since it has a much larger drive and ram. The desktop PC icon at the bottom right for tomtom now says your 1530 has been updated. The laptop states three updates now available, please connect your device. So, now think everything is okay.I have saved the instructions above as recommended by TomTom so next time is quicker!? What gets me is the darn thing updates for over four to five hours as if everything is going well and then says there was an interruption! Please try again! Thanks,
