Visual Mill software offer?

There is a free visual mill v3.0 from back in february, It had a month timer on it, Apparantly you could update it, but I never did. I just keep putting the date back to february and it works. I haven't explored it like I would like to, though. And it doesn't do the 4th axis like I need. I sure would like to start earning some money so I can buy one of the nicer 4th axis applications.
