Slider Position Keeps Changing

[highonclothing]

I recently purchased the "Underwear For Men" template for prestashop and am having one huge issue. There are two sliders which are side by side on the home page, see the live demo from template monster ( http://livedemo00.template-help.com/prestashop_40731/ ). I installed the theme, and everything worked fine. As I began to add categories and upload my logo, the bigger slider moved over a bit, and the other slider is now underneath instead of beside it. In live edit, neither module can be edited...PLEASE HELP. I have created a temporary user for my site (since it is in maintenance mode). If anyone can help, i will send you the login information so you can take a look. PLEASEEEEEEE. www.highonclothing.com/admin123 is the login url. THANKS. I added a screenshot below of my website.
