my brother also plays but on another account.
however, the server does not recognize that its two different accounts and doent let me vote for it on my account. :/

Maybe it looks at your Ip adress to see how many times a person voted on that computer? Did you try using a diff. comp?

Hotspotshield? That might help seeing as it will mask your IP address.
