Twentlytwelve Child theme style sheet won't upload via ftp

I have created and uploaded multiple child themes before, and this is my first time running into a problem where when I attempt to upload the style.css file for the child theme through Dreamweaver, I get an error message saying “file may not exist or you may not have permission”. I have tried renaming the file and the file folder, all to no avail.

This is what the css file looks like:

Theme Name: Twenty Twelve Child
Description:    Child theme for the Twenty Twelve theme
Author:         Leila Rand
Template:       twentytwelve
Version:        0.1.0
*/

@import url("../twentytwelve/style.css");

After looking through the forum, I see that other people have had success fixing this by changing the text encoding of the file – which I have never had to do before. My choices in Dreamweaver are:
– None
– C (Canonical Decomposition, followed by canonical composition – this is the default
– D (Canonical Decomposition)
– KC (Compatability Decomposition, followed by Canonical Composition
– KD (Compatability Decomposition)

there is also a checkbox for Include Unicode Signature (BOM)

Do you think any of this could be the problem? Any advice?
