Issues with code challenge in 'advanced selectors' section.

When I finish up the first task of the code challenge (stage 3/advanced selectors), and moved to task 2 and click "Check Work", it keeps telling me the following:

Oops! It looks like Task 1 is no longer passing.

I've redone step #1 about four times now, which I get right, but when I do step #2, even though it is correct, I get that error. Is it a bug perhaps? Or am I not doing something right?

I've input the code below.

index.html 
<!DOCTYPE html>
<html>
<head>
    <title>Structural Pseudo-classes</title>
    <link rel="stylesheet" type="text/css" href="cc1-main-style.css">
    <link rel="stylesheet" type="text/css" href="style.css">
</head>
<body>
    <ul>
        <li>List item 1</li>
        <li>List item 2</li>
        <li>List item 3</li>
        <li>List item 4</li>
        <li>List item 5</li>
        <li>List item 6</li>
        <li>List item 7</li>
    </ul>
</body>
</html>
style.css 
/* Write your CSS below */
li:nth-child(3) {
  background-color: #FF6347;
}

looks like you erased the css you wrote for step one. be sure to leave 

li:nth-child(even) {
  background-color: black;
  color: white;
}

Did you delete the rule that you created in the first task? If so then that is your problem, remember the instructions asked you too create a new rule. So re add the rule from the first task and see if that works.
