Why would my try-catch block still be throwing an error when it's handled?

Exception Details: System.NullReferenceException: Object reference not set to an instance of an object.

              Try
    Here >> :   _MemoryStream.Seek(6 * StartOffset, 0)
                _MemoryStream.Read(_Buffer, 0, 6)
              Catch ex As IOException
                        // Handle Error
              End Try

Edit: Cleaned the question up to remove the extraneous information.
