How to register a tileobjecttype?

Hallo.

If I have a tileType definition like this:

...
<TileTypes>
                <TileType>
                    <Index>0</Index>
                    <Material nameRef="_0_nixMaterial" />
                    <ObjectType>
                        <object objTypeRef="TileType" />
                        <object objTypeRef="VeneziaTileType" />
                        <object objTypeRef="vn_0" />
                    </ObjectType>
                </TileType>
...

an I try to load the scene:

TorqueSceneData sceneData = new TorqueSceneData();
            sceneData.DefaultTypeMap.Add("VeneziaTileType", typeof(VeneziaTileType));
            sceneData.Load(aMapName);

than I get the following error-message:

Quote:

how can i unlock the object database? or how can i register the objecttype before?
