I cant get a custom doodad to work

[Maridot]

I am sorry for having to ask something so simple, but I am trying to make a custom doodad work without success.
The doodad says it doesn't require a custom path in the guide but it says the file cannot be loaded/displayed.
The doodad in question would be this.

Am I just stupid or is there something more complex to this?
I would appreciate help, please.

Make sure you've done everything from HERE right, see if that works. If only this model makes problems for you, it's probably something wrong with the model itself. I could fix it for you if so.

Also, "Don't be afraid when you place the object and it appears to be a purple cube. Just close the map and open it again and it will look fine in the World Editor." make sure that isn't the issue.
