Its hard to know what to advise you since I don't know what you have changed.
ticktockpro in its original version is designed as a centered fixed width layout. The width of the centered section is determined by the #wrapwebsite selector in stylelayout.css, but also by the background image in styleimages.css
Since the background image is designed for a specific width you may not be able to use that image if you set a different width.
Modifying skins is a trial and error process even for me, but it does help if you read some of the good css books.
Hope it helps,
