I can't enter any yahoo chat rooms, there is no code for me to type...?

[Mystic Spirit]

I tried installing and reinstalling Yahoo Messenger, used multiple accounts and set the ignore list to ignore only the people listed below but nothing is working. I read the getting started guide saying that I need to enter a verification code when I enter a chat room, but the problem is there is nothing showing up in any chat room, there is no links, no code, etc... Help?
