I get the same thing. It's not your fault nor are you doing anything wrong. I e-mailed Luke and he said that the PM function has been disabled for anyone who joined after, I think June 15th. So if you became a member here after that date, like I did, you don't have the PM option. It has to do with bandwith and storage space on the server, or something like that.
Anyway, you can, if the person you are trying to contact has it turned on, send them an e-mail. If not, just try and get their attention in the Off Topic forum.

It's not broken. Like James said, it's been disabled for all forum members registered in the past few months, due to bandwidth constraints, the usefulness of PMs (or rather, the lack thereof), and the fact that certain spammers have abused them.
It really should be just as easy to e-mail your fellow forum member, and everyone can choose to make their address public or not.
