theme changes aren\'t saving

Hi there, I'm using Catch Kathmandu and when I go to make changes to my theme options (both the featured content and the featured slider) and I click on "save" I am taken to my homepage and when I return to the editing screen, none of the changes have been made. I have tried two different computers, reinstalled WP, logged out, etc. and it worked on his computer with his system. We are both administrators, so things should work the same for both of us. Any ideas? www.mts-seattle.org
