After sending a SymbolsForExchangeRequest to the server, I start receiving malformed messages amongst the SecurityDefinitionResponse replies, and importantly I never get the final response. Also an excessive number of bytes are being received from the server with each of these messages. Furthermore, when encryption is enabled the client crashes after it is unable to decrypt the server response. Here is the output from my program. This is using Binary encoding. ---------------------------------------------- Received 388 bytes from server: message of type: GeneralLogMessage and size: 132
