Marco, the reason I believe Bruce posted that article was to basically (and politely) say that you are responsible for investigating what s2Pro is capable of before purchasing it. You cannot expect a refund when a product does what it explicitly says it CAN do, but not what everything you wish it would do.
If I go and buy a soldering iron that advertises that it can weld solder, I can’t expect a refund because it can’t build me a circuit board without some work.
I appreciate/understand your frustration, but again – it is your responsibility to investigate (read – ask questions in the community forum) before you purchase s2Pro.
Another thing; if you think about it, it is almost impossible to give refunds for premium software purchases – even if I were to get a refund on my soldering iron, the store would at least get their merchandise back. With software, not so. If you were to get a refund now, you could potentially happily continue to use said software – which has basically now become free software – and whomever you may decide to share it with.
