TOMTOM Navigator 6 'Maps Not Found'

Help!
I have a XDA2i with TomTom navigator 6 it worked fine untill the sd card died,
i got a new SD card, loaded tomtom from backup of sd on my pc.
TomTom has loaded ok but cant find the maps.
I have been told to put the maps on the sd card but i have tried everything to get them to load and still nothing but 'No Maps Found'.
I have to agree to the Legal Notice, So the software is fine.
Please help a very fustrated (and struggling with paper maps)soul.

Can you view the contents of the SD card using File Explorer on the device, if so is the map folder in the root of the memory card - if its placed into any folder on the card making the map folder a sub folder then the application won't see the map - Mike
