Cannot make two columns of articles.

I cannot find this file. I searched using my ftp program and in the file manager in cPanel. There seems to be no com_content folder or blog.php file within the hot_software template. Please see attached files. Am I looking in the wrong place? What should I do next?
Thanks.

Please re-download and re-install template because we've fixed bugs some time ago. If it does not work, please give us link where the problem exists on your site.

Did as you suggested. Uninstalled and reinstalled the template. It did not resolve the problem. All settings are exactly as before and I still have only one column. The problem exists on all pages. See at my site ' www.gregses.com '.
One column is OK as I like the template, but two is preferable. What else can I try? Also, I downloaded and installed the hot_software25.zip file, but in the 'Extension Manager: Manage' section it indicates it is version 1.6. Is this OK?

Please edit file /templates/hot_software/css/template_css.css and add this code:

Thanks. This worked. Now I can make 2 columns. However, now the shaded grey area behind the main content is affected. As you can see from the attached file, the two column pages grey background is not in position correctly. The one column pages are no problem. Is there any way to fix this?

Try this changes:

layout.css:

.content_wrap_bottom {
background: url(../images/content_border_bottom.png) no-repeat bottom left;
}

.content_wrap {
background: url(../images/content_border.png) repeat-y;
margin-top: 30px;
}

clear all properties from this css entities. Remember to backup or comment using /* commented content */ so you can un-comment later
