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?

You need to register each account before you can use it on that computer. It asks for the account number. Do that and it will work.
