IBMDA400 Provider Returns Question Marks in Some Fields Instead of Data from AS/400 File Using MS Access VBA

The IBM400 provider used in the code in the snippet to pull data from an AS/400 file created by an AS/400 query suddenly (today) pulled question marks instead of the data from some fields in the file. The data is correct when pulled using Client Access (iSeries Access) Data Transfer into Excel. The fields that return as question marks are defined result fields in the AS/400 query using character data. Any idea why this would suddenly happen today?

Public Function AS400GetData(ByVal strUserName As String, _
  ByVal strPassword As String, ByVal strSQL As String, _
  ByVal strSystem As String, ByRef avarData() As Variant) As Boolean
' set up error handling
On Error GoTo ErrorHandler
    ' set the initial state of the function
    AS400GetData = False
    ' open a connection to the AS400
    Dim cnn As New ADODB.Connection
    cnn.Open "Provider=IBMDA400;Data Source=" & strSystem & _
        ";User ID=" & strUserName & ";Password=" & strPassword & ";"
    ' using a recordset, get the data and field names
    Dim rst As New ADODB.Recordset
    With rst
        ' open the recordset
        .Open strSQL, cnn
        ' if data was found,
        If Not .EOF Then
            ' get the data
            avarData = .GetRows
            ' eliminate leading and trailing spaces in the data elements
            AS400TrimData avarData
            ' indicate data was retrieved
            AS400GetData = True
        End If
        .Close
    End With
    ' close the connection
    cnn.Close
    ' clean up
    Set rst = Nothing
    Set cnn = Nothing
ExitHere:
    Exit Function
ErrorHandler:
    MsgBox "Error:" & err.Number & vbNewLine & _
        "Description:" & err.Description & vbNewLine & _
        "From:" & err.Source, vbExclamation, _
        "AS400GetData Failed"
    Resume ExitHere
End Function
