ok guys i have a big problem.

I want to purchase the Rainbow from the 5000 DMM Points Deal.

I tried 2 Creditcards (my own, Visa) and the Creditcard from a friend of mine (Mastercard).

DMM doesn't except either of them.

What should i do?

Do you guys use a Proxi Server where you change your IP to Japanese or something?

Did you encounter such problems in the past?
