Can't Select Checkbox, Selenium WebDriver

I am unable to select a checkbox with Selenium WebDriver in Java. I tried by Xpath but no result. WebDriver can't click on element. I tried with Selenium IDE - recorder, no results.

Here it is - html code for checkbox Code Box

I try:

1. driver.findElement(By.xpath(".//form[@id='placeOrderForm1']/div[@class='terms right']/label")).click();

2.driver.findElement(By.id("Terms1")).click();

3.driver.findElement(By.cssSelector("label")).click();

4. driver.findElement(By.xpath("//div[3]/form/div/input")).click();

Nothing works. Please help.
