he did not do anything wrong. He is allowed to put the script on any site he wants. Even yours for a charge. I am in the same boat as you. I paid for classipress but i dont get support, although mine does update when new versions come out. I wish I could see all the threads so i can make more improvements to my site but thats just not going to happen. But from using clasipress i realized how much I love AppThemes work, so I will be looking to get the "Club Package" then I can see all the threads.
