Upgraded a theme and the content is squashed

Hi I upgrade Evada (I know this isn’t one of your themes but I just need someone to check the code). After I upgraded the all the copy on the homepage http://www.talga.com.au is now squashed to the left hand side. I am a mere designer and don’t know much about code, hence me having a membership with you guys as you have helped me with CSS before. Is also occurred on about page,

Hope you can assist me as the I have contacted the theme developers yesterday and haven’t heard anything, cheers
