DropBox API Async Call, "DropBoxClient.Files.DownloadAsync" will not throw an exception (solution)

Here is my code...

        Private Async Sub Dropbox_DownloadApplicationFiles(ByVal poDropboxMethodDataStructure  As DropboxMethodDataStructure)

            Dim liResult                      As Integer = 0
            Dim lsApplicationDirectory        As String = My.Application.Info.DirectoryPath + "\"

            Dim loFileByteArray               As Object

            Dim loDropboxMethodDataStructure  As New DropboxMethodDataStructure()

            Dim loDropBoxClient               As DropboxClient
            Dim loDropBoxClientResponse       As Object


            Try

                loDropboxMethodDataStructure.RESULT = 0

                loDropBoxClient = New DropboxClient(csDropBoxUserAccessToken)

                For Each lsFileName As String In poDropboxMethodDataStructure.FILE_NAMES_ARRAYLIST
                    ' test for existence of dropbox file  (if file not found (path not found error), this async call will throw an exception
                    loDropBoxClientResponse = Await loDropBoxClient.Files.GetMetadataAsync("/CDOCS" + "/" + lsFileName)

                    ' download dropbox file (this async call will NOT throw an exception
                    loDropBoxClientResponse = Await loDropBoxClient.Files.DownloadAsync("/CDOCS" + "/" + lsFileName)

                    ' write dropbox file to application directory
                    loFileByteArray = Await loDropBoxClientResponse.GetContentAsByteArrayAsync()
                    System.IO.File.WriteAllBytes(lsApplicationDirectory + "\" + lsFileName, loFileByteArray)

                    ' TESTING ONLY !!!
                    If (lsFileName.Equals("CDOCS.exe")) Then
                        Exit For
                    End If
                Next
            Catch loDropboxException As DropboxException
                loDropboxMethodDataStructure.RESULT = -2
                loDropboxMethodDataStructure.METHOD_MESSAGE = "APPLICATION UPDATE ERROR!!!  (Method: Dropbox_DownloadApplicationFiles): " + loDropboxException.Message + Environment.NewLine + Environment.NewLine + "Please contact Black Falcon Software..."
            Catch loException As Exception
                loDropboxMethodDataStructure.RESULT = -1
                loDropboxMethodDataStructure.METHOD_MESSAGE = "APPLICATION UPDATE ERROR!!!  (Method: Dropbox_DownloadApplicationFiles): " + loException.Message + Environment.NewLine + Environment.NewLine + "Please contact Black Falcon Software..."
            End Try

            liResult = loDropboxMethodDataStructure.RESULT

            If (liResult < 0) Then
                Console.WriteLine("")
                Console.WriteLine("")
                Console.WriteLine("")

                Console.WriteLine("")
                Console.WriteLine("Press any key to end application...")

                Console.ReadLine()
                End
            End If


            ' ---
            ' end of async processes -> display success message
            ' ---
            Console.WriteLine("CDOCS Application update completed successfully... Please press any key to launch the CDOCS application...")
