Trouble Installing Thematic Child Theme

I am new to WordPress, but I have searched up and down for the solution for my problem and no other issue seems to be similar to mine.

I copied the “thematicsamplechildtheme” folder info (style.css, readme.txt and functions.php) into my new child theme’s folder in the root level of wp-content/themes just as the readme instructed.

However, when I go to install the theme on my WordPress page it says that the theme is installed by incomplete because the stylesheet is missing.

This is the stylesheet provided with my edits. Again I am completely new to this so it is very possible that I just don’t see something:

/*

/* Apply default theme styles and colors */
/* It's better to actually copy over default.css into this file (or link to a copy in your child theme) if you're going to do anything outrageous */
@import url('../thematic/library/styles/default.css');

/* Prepare theme for plugins */
@import url('../thematic/library/styles/plugins.css');

/* Overriding Thematic's styles for congruity with WP-Admin > Appearance > Header default header text color settings */

Thank you for your help!
