Kubelwagen 3do missing in Centauro

[SilverSV]

TOW2 Africa works perfectly but when I install Centauro it ctds on scenarios with kubelwagens. There is a kubelwagen entry in the encyclopedia but no 3d object. The picture's black. If I click open hatches, it then ctds.

I have installed with all security software disabled and tried compatibility and digital rights correction solutions and the problems still exists.

Could the problem be an umlaut filename issue?

Windows 7 64, i7, 8gig, radeon 6770m.

TOW2 Africa without centauro does have the kubelwagen 3do and works fine.
What's different about Centauro?
