It's safer to buy the software. you never know what could be encrypted on a bootleg. Plus what happens when you need support on it. Do ou call the manufactuer and tell them hey my bootleg copy doesnt work.
If you are looking for a good cheap way off getting some software is getting it through a student.
If you know any person who is currently enrolled in a any college class, they can buy a copy of the entire Adobe Suite for only 200.00 Dollars. mean full access to it only difference it is a student license. but you can live with that.
