30 min web page load times

Hello, I have a problem with load times for a web game. Every othe site is fine, but when I go to this one, ijji.com or gunbound.ijji.com, or gunster.ijji.com, it will take 30min to load fully, in firefox it works fine but it only works in internet explorer, I have changed every I possibly could to aloow cookies, etc. The only thing I can say is the site doesn't have a certificate, mayne thats why, can someone plz help, i like gunbound ans gunster a lot.
