[TDR]

From what I can see the scenario uses the kbDataModern database.
The scenario zip file only provides 3 of the 5 files of this database.

As far as graphics goes you may need that as well.

Just an brief observation with out running the scenario.

Additional comment:
dont forget you need to also down load:
Deltapooh's Vehicle Pack Pt 1
and
Deltapooh's Vehicle Pack Pt 2


All assumes the scenario is complete etc.
