Have lost all maps and other non default settings. Restore is corrupt and cannot be used to fix issue. Have copies of files from TomTom on computer but cannot restore them using the TomTom Home interface.

Would like to recover maps, configuration, settings and voice downloads that I have purchased in the past.

My questions are twofold-

Is there anyway to recover and place these files on my TomTom?
If that is impossible to do from my computer is it possible to get another copy of these files from TomTom?

Thank you for your time and assistance
