That's really sad indeed. They are people pirating Amiga software, when the original is less than 10 euros? Hahaha, how "gypsy" they are. Anyway, I have also my original copy, it came together with a 40GB 2.5" HD for my A1200 from AmigaKit.
Good luck too! But that's a really shame for someone to distributing pirated copies of any Amiga-software.
