AT+CIPSTART link type error

[yaronze]

Hi,
i am using the SerialESP8266wifi.h library with Arduino UNO and ESP8266 module.
I uploaded the library example sketch into the Arduino.
I got link to WiFi network and got IP address just fine. also i ping it and got response.
While i'm trying to connect to server using connectToServer, i am receiving a message - Link Type Error in the serial monitor.
I succeeded to conect to the server same IP and Port using Hyper Terminal but still got the Error from the ESP8266 and Arduino.

any suggestions?
thanks in advanced.
