What happens when you go to Operate My Device in TT HOME? Does it show the map, or the same message you've got?
Worst case scenario, try this:
1. Save everything from the device, using Explorer (or Finder on Mac), include all the files (hidden as well). It is also known as a manual backup: http://uk.support.tomtom.com/app/answers/detail/a_id/13354/
2. Then format the internal storage (or memory card, depending which one you use) of your device. http://uk.support.tomtom.com/app/answers/detail/a_id/16172/
3. Go to TT HOME, Manage my "DEVICE", delete everything from the hard drive and try the update again.
4. Copy your voices and post codes back to the devices (also the maps if that didn't download either).
