Cannot make two columns of articles.

I recently installed the Joomla 2.5 Hot Start pack for this template, but when I apply the blog layout, I cannot make two columns. My site only has one column of articles in the content area for all pages. However, in other templates the two columns appear.
While not a complete beginner, Ive used Joomla 1.5 before and am guessing this problem might have something to do with the CSS or source code, which I don't know much about.
How can I fix this?
Your help would be greatly appreciated. Thanks.

Are you sure that you entered correct numbers for columns in the parameters of the Blog's menu item? We need your link to inspect that.

The link to my site is www.gregses.com . The frontend is in Japanese, but the backend is in English. As you can see from the image file attached, the columns are set to 2 in the Blog Layout Options section. The site is only partially made, but if you click on either of the two menu items on the left side of the page there is only 1 column, despite both menu items being set to 2 columns. I am at a loss as to what I am doing wrong. Thanks for your help.

Try general settings for "Blog / Featured Layouts" when you enter article manager there is "options" icon , and when you click on it you will find that tab.

Thanks for the suggestion, but unfortunately it still won't create two columns. I've included an image file of the settings in the options Blog / Featured Layouts box.
It looks alright to me. If nobody else is having this problem, I am wondering if you think there is any value in deleting this template and reinstalling it again. Perhaps something was amiss with the initial installation.

Try this open:

\templates\hot_software\html\com_content\category\blog.php

around line 51:

if ($this->params->def('multi_column_order', 0)) : // order across, like...

change to:

if ($this->params->def('multi_column_order', 0) || true) : // order across, like...
