If you are using commercial software without paying for it, and that information is brought to light, the company has the right to prosecute you. You may lose everything. If you can't afford the price of the software, don't use it. Look for a free alternative. Again, the first suggestion I gave you is free and open source.
Check out alternativeto.net for good replacements. Most free options won't have all the features of the commercial version but will get you what you need until you can afford the price tag for the paid program.
I just want to point out that, you are trying to make a COMPUTER PROGRAM which, if you intend to sell, will become part of your income. How would you feel if you found out that your hard work was pirated? Piracy is not a "victimless crime." It is just a crime.
