1) this program is FREE, but if anybody like it, there is a possibility to DONATE to support development because it takes a lot of time to make it. Get the dictionary to find out what the word means
2) some people donate because they like it, I can then add more hosts what they like ... as my appreciation that anybody supports development I give a registration key to open some special functions
3) if you are the "cheater", I don't suppose you would confess ... if not ... there is a person, who donated to support my project and then complained to get money back. The person used the same address as you (so it is 99% you). If not, you are unlucky, because I won't allow you to upload from that address unless you pay off the trouble that person caused me.
