I looked up the laws in New York (other states may vary), and you can recover your damages or $500, whichever is greater. You have to prove that the advertiser knowingly misled you (which software bugs probably aren't), and that the false advertising is what influenced your purchase. I doubt it's likely to succeed. Everyone on the jury will be easily convinced that software is hard to get right, since they have probably used a lot of shitty software and consider it normal.
