It looks as though not all of the Contact Form Solution Pack files and folders have uploaded to the same directory on your server. Your 'SpryAssets' folder is in the root directory of your site, while the other CFSP folders are in your 'Contact_2009' folder.
Try uploading the 'SpryAssets' folder into your 'Contact_2009' folder along with the other CFSP files and folders. You will need to adjust the paths to these SpryAssets .js and .css files in the head of your involve_join_2010.php page to point to the new location. ( 'SpryAssets/ . . . ' instead of '../SpryAssets/ . . . ')
