ChromeDriver doesn't click on element. Selenium. Java

I am making scenario to automatizate some actions on this site https://csgo500.com/

Code of my class:

package scenario;

import managers.loaders.CheckBy;
import driver.sleep.DriverSleeper;
import exceptions.NotNowException;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;


public class CSGO500Scen implements SiteScenarioInt{
    private WebDriver driver;

    public CSGO500Scen(WebDriver driver){
        this.driver = driver;
    }

    public void gamble() throws NotNowException {
        driver.get("https://csgo500.com/");

        CheckBy.id("gotit-btn");
        driver.findElement(By.id("gotit-btn")).click(); //accept terms of use
        DriverSleeper.sleep(3);

        CheckBy.id("content-login");
        DriverSleeper.sleep(3);
        driver.findElement(By.xpath("//*[@id=\"content-login\"]")).click(); //HERE IS A PROBLEM

        CheckBy.className("btn_green_white_innerfade");
        driver.findElement(By.className("btn_green_white_innerfade")).click(); //login with steam

        CheckBy.className("nav-rewards");
        driver.findElement(By.className("nav-rewards")).click();

        if(!isActive()){
            throw new NotNowException("CSGO500.com");
        }
        else{
            while(true){
                DriverSleeper.sleep(3);
                if (!isActive()){
                    break;
                }
            }
        }
    }

    private boolean isActive(){
        if (driver.findElement(By.id("reward-claim-submit-disabled")).getAttribute("style").equals("display: none;")){
            return true;
        }
        else{
            return false;
        }
    }
}

First step is to Accept Use Terms. Ok, it's done, but when i want to click on "Login" button, i get following error(Login button id is "content-login") :

Exception in thread "main" org.openqa.selenium.WebDriverException: unknown error: Element <a id="content-login" href="http://ift.tt/2royEJ8" data-lang="login" class="" data-__original="
...
" data-__trid="1000018" data-__translated="en">Login</a> is not clickable at point (946, 33). Other element would receive the click: <div id="login-content">...</div>

It writes that this page contains one more element with the same id. I have written Test to get number of elements with this id:

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;

import java.util.concurrent.TimeUnit;
public class test {
    public static void main(String[] args) throws InterruptedException {
        System.setProperty("webdriver.chrome.driver", "C:\\Users\\user\\IdeaProjects\\sitescen\\src\\main\\resources\\chromedriver.exe" );
        WebDriver driver = new ChromeDriver();
        driver.get("http://ift.tt/1UtLAUt");
        driver.manage().timeouts().implicitlyWait(5, TimeUnit.SECONDS);
        System.out.print(driver.findElements(By.xpath("//*[@id=\"content-login\"]")).size());

    }
}

I got output:

1

So, i have only one element with the same id, and no elements arround this button.

To prevent errors of loading, i use sleep of my DriverSleeper class which accept number of seconds to sleep.

Finally, i don't know, how to click this button, and hope, that you help me.
