Problem with multiple ds18b20 connection

Hi there, I’m trying to connect two ds18b20 on OneWire, but it’s not working. I’ve found an example of multiple using :

#include <OneWire.h>
#include <DallasTemperature.h>

// Data wire is plugged into pin 2 on the Arduino
#define ONE_WIRE_BUS 2

// Setup a oneWire instance to communicate with any OneWire devices (not just Maxim/Dallas temperature ICs)
OneWire oneWire(ONE_WIRE_BUS);

// Pass our oneWire reference to Dallas Temperature. 
DallasTemperature sensors(&oneWire);

void setup(void)
  // start serial port
  Serial.println("Dallas Temperature IC Control Library Demo");

  // Start up the library

void loop(void)
  // call sensors.requestTemperatures() to issue a global temperature 
  // request to all devices on the bus
  Serial.print("Requesting temperatures...");
  sensors.requestTemperatures(); // Send the command to get temperatures
  Serial.print("Temperature for Device 1 is: ");
  Serial.print(sensors.getTempCByIndex(0)); // Why "byIndex"? You can have more than one IC on the same bus. 0 refers to the first IC on the wire

but it says no matching function for call to 'DallasTemperature::DallasTemperature(OneWire*)'
Correct, as i think, version of DS library i’ve downloaded from, this link is given here, so as the sketch too.
What can be a problem? I’ve read .h file, but the function given before exists there(,

That's version 1.5.0Test. The latest version is 3.7.1Beta:

The latest non-Beta version seems to be 3.6.0:

Yes, the newer version helped, it works!, but i have one more question.
Why does IDE compile and uplode sketches a bit too long on my Windows 7, x64??? On XPs it's OK, and I've heard that on W7 also)
