InterPoker - can't login with different screen name?

I'm trying to login to InterPoker on my friend's laptop with my screen name and it says the account is unknown. However, if i try to login with the exact same userid and password on the computer on which I registered, it works fine.

Do they really have it setup so that you can ONLY login to InterPoker software on the computer on which you registered?!

Any help?
