Can't create child theme even when parent theme is present.

I have Cygnus from ThemeForest installed.

The Cygnus theme folder is named “cygnus”.

I created a child theme with the following style.css:

/*
Theme Name: Secure2Go
Version: 1.0
Template: cygnus
*/
@import url(‘../cygnus/style.css’);

#logo img {
width: auto;
height: 54px;
}
#bottom-wrapper, a.more-link, .post-type, .button.green {
background: #89CFF8;
url(none);
}
a:link, a:visited, a:active {
color: #89CFF8;
}
.special-title h1 span, .special-title h2 span, .special-title h3 span, .special-title h4 span, .special-title h5 span, .special-title h6 span {
border-bottom: 4px solid #89CFF8;
}
.link-more, li.link-more {
border-bottom: 5px solid #89CFF8;
}

I initially used Notepad++ to create and save this file. I saved it with ANSI encoding.

WordPress admin appearance>themes says the child theme is broken because the parent theme is not installed.

The parent theme *is* installed.

I tried saving style.css in Notepad2, and Dreamweaver, and in both cases the error remains.
