Error: No Type Code for 'Class'. Check NDOTypes.xml

Hello,
I got the Error when i write my Data:
Message="No Type Code for Brunken.Vertragsmanagement.Vertragsdaten.Firma. Check NDOTypes.xml"
Source="NDO"
ErrorNumber=94
StackTrace:
       bei NDO.Mapping.TypeManager.get_Item(Type t)
       bei NDO.PersistenceManager.WriteMappingTableEntry(MappingTableEntry e)
       bei NDO.PersistenceManager.UpdateCreatedMappingTableEntries()
       bei NDO.PersistenceManager.Save()

My Modell looks like this: The baseclass Vertrag (is not abstract) has a n:m Relation to the class Firma. Also I have subclasses of Vertag: Darlehensvertag and Versicherungsvertrag.

In my test programm I write Data into my Classes.
            PersistenceManager pm = new PersistenceManager();

            pm.BuildDatabase();

            Firma geselschaft = new Firma();
            geselschaft.Name = "Gothar";
            geselschaft.IstVermittler = false;
            pm.MakePersistent(geselschaft);

            Firma vermittler = new Firma();
            vermittler.IstVermittler = true;
            vermittler.Name = "Sicherheit und Finanzen";
            pm.MakePersistent(vermittler);

            Vertrag vertrag = new Vertrag();
            vertrag.Begin = DateTime.Now;
            vertrag.Bezeichnung = "Hundehaftflicht";
            vertrag.AddFirma(geselschaft);
            vertrag.AddFirma(vermittler);
            pm.MakePersistent(vertrag);
            pm.Save();

Why did I get this Error?
