Problem with r4iGold wood cc, please help

Hi, I have a big problem: I have a R4iGold Wood I just buyed, it says the page that gives the official kernel is www.r4igold.cc, it´s a yellow one. But, when I´m going to push the Konami Digital Entertainment button on my DSL, the screens go black and nothing happens.

I´ve tried formatting in windows and with SDFormatter v4, puttin it the original kernel from its web page (v2.50), other Wood versions (v1.64, v1.6) and nothing happens.

Could you please...
