Creating a Multileader Style - Answered

Hello,
I have a function that creates the multileader style for my drawing. It works in AutoCad, but in BricsCAD it crashes at the line:
newStyle.TextAttachmentType = TextAttachmentType.AttachmentMiddleOfTop

Public Sub AddMleaderStyle(ByVal dwg_scale As Double)
Dim podDWG As Document = Application.DocumentManager.MdiActiveDocument
Dim podDB As Database = podDWG.Database

    Using mldrTrans As Transaction = podDB.TransactionManager.StartTransaction()
        Const styleName As String = "Amkor"
        Dim mlstyles As DBDictionary = CType(mldrTrans.GetObject(podDB.MLeaderStyleDictionaryId, OpenMode.ForRead), DBDictionary)
        Dim mLeaderStyle As ObjectId = ObjectId.Null

        If Not mlstyles.Contains(styleName) Then
            Dim newStyle As MLeaderStyle = New MLeaderStyle()
            Dim txtStyleTbl As TextStyleTable = DirectCast(mldrTrans.GetObject(podDB.TextStyleTableId, OpenMode.ForRead, False), TextStyleTable)
            Dim mTxtStyleId As ObjectId = txtStyleTbl("Romans")
            newStyle.TextStyleId = mTxtStyleId
            newStyle.ArrowSize = 4.4
            newStyle.DoglegLength = 5.0
            newStyle.EnableLanding = True
            newStyle.LandingGap = 1
            newStyle.TextHeight = 2.2
            newStyle.TextAlignAlwaysLeft = False
            newStyle.TextAttachmentType = TextAttachmentType.AttachmentMiddleOfTop **'<--Crashes here**
            newStyle.SetTextAttachmentType(TextAttachmentType.AttachmentMiddleOfTop, LeaderDirectionType.LeftLeader)
            newStyle.SetTextAttachmentType(TextAttachmentType.AttachmentMiddleOfTop, LeaderDirectionType.RightLeader)
            newStyle.Scale = dwg_scale
            mLeaderStyle = newStyle.PostMLeaderStyleToDb(podDB, styleName)
            mldrTrans.AddNewlyCreatedDBObject(newStyle, True)
        Else
            mLeaderStyle = mlstyles.GetAt(styleName)
        End If
        podDB.MLeaderstyle = mLeaderStyle
        mldrTrans.Commit()
    End Using
End Sub

I would greatly appreciate some help/direction on this, thanks.
