I don't see that the poster has an issue opening the site, only using it?
But fwiw, the address you have has a typo, as you can see. When I went to .com, it opened fine.
I could not follow through, to check your problem, as it would mean registering, which I did not care for, but it was apparent, from the home page and subsequent pages, that it was heavy with Java. Perhaps you could try updating that?
