I have purchased the license for iGG 8.3 in ( https://igg-server.herokuapp.com/ ) : 3$ through Aqua Wu ( the iGG developer ) payment method as he posted on his blog spot ( https://igg-server.herokuapp.com/ ) , my error is Initialization failed : Please contact the developer for help , after that i send him an e-mail with my MAC address and my TRANSACTION NUMBER to him . after waiting 4 hours I received a reply from him, and he said : Reset the database and launch IGG 20 times and I have followed , I launch IGG 100 times but still failed as above , I send email for him one more time but still have not received the answer . Let me ask if anyone is faulty like me and fixes the error successfully or if anyone here purchased it successfully , please tell me what should i do now ? or if you guy can contact him , please help me !
