I guess as I've heard the Japanese codes are useless in US. Today I got a "Your account has been deleted" email from Konami.

i downloaded and installed the beta just fine with my JP code. Can't test to see if I can login, but I ran the game and downloaded the 1.01 update and everything. I have a US konami id, and JP one, so hopefully either will work, won't know until the 21st.
