Footer 3 Widgets Not Displaying in 3 Columns

Hello, first of all, great job with the Adventurous Theme! I am building a site for a client and a few days ago I had the footer widgets displaying properly in 3 columns with one widget in each column (no widget in the 4th column). But I've been applying some CSS changes to other plugins and now I see that the 2nd and 3rd widget are grouped in the second column. I didn't edit footer.php and I can't figure out what I did wrong to get this outcome. Can you help? the site: http://www.vibgyortech.co.uk/asianconf/ http://jammin.smugmug.com/photos/i-NJRtwBc/0/L/i-NJRtwBc-L.jpg http://jammin.smugmug.com/photos/i-djZDgpk/0/L/i-djZDgpk-L.jpg
