Problem with new terrain

[nucleon2]

Hello everybody.

I'm trying to create a new terrain for the fun but i've got some problem. When i try to switch to it in Falcon, i've a error message:
No such file or directory: couldn't read offset block

Any idea ?

I've followed the installation procedure "ultimate terrain creation".

this is a short description of my directory (from installation path):
campaign/
save
balkans
scan (this is me terrain)
art
art1024
artbalkans
artscan

etc...

My config:

128 Mo, DD 15 Go

If anyone has an idea

I've tried to rebuilt a new theater for falcon. In fact in the tacedit when i try to build the occupation map, where the progress bar reach 50%, tacedit crashes with an error msg from window (at this location the memery can't be read....)

What's wrong
