Child Theme Style Sheet not loading

I made a child theme for twenty twelve, created a web site, added content, edited the styles in the child theme style sheet. In short I had a working site.
I found a little snag where the site was not loading right on another computer on google chrome. It was strange because it loaded completely fine on my computer in every browser I tried it on, and on my iPhone. I used chrome, firefox, safari, and IE.

So I went about trying to edit the stylesheet to make it look correct. It was a matter of setting the width for something, I didn’t end up figuring out what happened.

In the process of trying to figure it out, my child theme stopped loading the child style sheet all together. I tried several things to make it work, and considered exporting the content, re-installing wordpress and editing the files one at a time again. I was hoping to avoid that.

I tried changing the permissions on the folder and files for my child theme, with no luck.

The web site is http://www.laucinaristorante.com

What really gets me, is it was working, and then it wasn’t. I don’t know what to do about it.

Thanks
