Also, have you tried a virtualization program like VM Ware or VirtualBox? It's like a computer within a computer, and it's free. It's great, you can install Windows XP on your machine "on top of" Windows 7 without screwing anything up. You run the VM sofware from within Windows 7, like an app, but you have a whole, self-contained "computer" in there.
Lastly, if you want, you can give me your professor's name and email address, or what school they teach at. I will write a very nasty letter about how they're teaching you on 20-30 year old tools that nobody uses any more, ensuring you come out with no marketable skills, all because they're too lazy to update their own skill set. There are many free options out there for graphics programming.
