Check out the company website - they do Dark Basic for schools, so they MAY sort you something out.
FPSC is unusual in its licensing agreement - as its royalty free etc, the TGC guys have really gone out of their way to make an approachable and accessible product here, I quite fancy your chances tbh.
Theres a business support email form on their website - point your teacher to that.
Good luck.
I wish we had FPSC when I was at school!! Although saying that we didnt even have WINDOWS when I was at school!
Pffffffff - anyway..........
