I am installing inApp purchase in My app.Yesterday code was running fine and I tested it under sandbox environment. But today when i try to purchase product I am getting -1202 Error from iTunes.
I also googled for answer and refer apple doc but didn't find error code.
I had this problem on a customer's pc: the problem was caued by wrong date/time or zone settings.. I changed pc settings with the correct timezone (and obviously date and time), rebooted and the problem was solved.
