The keygen does not look for the Meta.txt in the map folder. It looks for it in the Progs folder. Check that it is in there and leave it there. If you are using the Official Navcore v8 as downloaded from TomTom Home, the keygen will NOT patch it. It WILL patch official Navcore v7 though.

Look at this post:
