Sorry to be a pain but i think I'm almost there......

I downloaded all parts of Europe 965.7250, and unzipped.
I formatted a new SD card to FAT32.
I copied all of the files that were unzipped to the root of the new card.
I then downloaded the Fastactive from the link above and copied this to the SD card.
Inserted the card in the TT, connected via usb and turned on.
Windows opened an F andG folder window in explorer. F for the card and G for the unit.
I started Fastactivate and it found the unit as G. I ran 1,2 and 3. all seemed successful.
I disconnected the unit and restarted.
Initially it loaded the North America map and when i tried to switch in preferences, the Europe map wasn't shown.
I made a new folder on the card called 'Europe' and copied all of the files that were unzipped to this folder.
Now the unit shows 'Europe' as an option to switch to, but when I try to switch I get 'PROBLEM WITH MAP - YOU CANNOT USE THIS MAP ON THIS DEVICE : EUROPE-100654
I tried re-running FASTACTIVATE and picking F to push it towards that map, but its not interested and just loops back until you pick G for the unit.

Any ideas?
