So comment out, delete or in other way destroy that line with jQuery 1.4.2 from Google.
The colorbox stuff is also weird. Like theme expect you to have Colorbox loaded. You have but from Lightbox Plus not theme. I will guess it all has to do with portfolio template or something? jQuery load is part of Nivo slider – which is old as well. You have 2.7.1, latest with jQuery fixes is 3.2 http://nivo.dev7studios.com/changelog/
Nivo files are in /themes/hcecobuilders/js/ folder and I dont think file names have changed so you can probably just overwrite old with new 3.2 versions. Notice 3.2 have a fix for jQuery 1.9 and you will want that sooner than later.
http://ascendworks.com/ they made theme? Seems more in to selling stuff but base is Genesis so update/fixes should be possible. Or if they are unavailable you can probably get help at Genesis forum. Only need to fix that 1 line, plus some worry about old Nivo.
