An error occurred with Rumble Fighter

Hello,
Today, I was trying to login but when the game started up the following error message displayed on the screen. How can I fix it? Have you any idea to resolve this issue? Any idea would be really appreciated. Thanks. I am running Windows 7 Operating System.
