It looks like you just joined Kongrege a few days ago (on the 11th). Welcome aboard.
What probably happened is that you deleted your cookies or used some other computer to get onto Kongregate. Most game on the site (all of them that aren't housed on a developer's remote server) store game data locally on your computer via a cookie. So if you move to a different computer, delete cookies, or even use a different browsers (Chrome vs Firefox for example), it won't pull up your saved game data.
I didn't find the right solution from the internet.
