Hello. Some problem happened during your payment automatic registration. We've processed the license manually. Now you should be able to see the app in your purchases list. Feel free to contact us via PM if you need some help.
Yes it seems you have different people responsible for replies. I have bought two licences one is installed and operating already on one domain how to install it on the other domain?
Hello, you just need to go to your second Studio (which uses different Key&Secret pair) -> Market Apps -> Purchases and download the app. In this case the second (not used) license will be used to download the app.
