Hi subratabera. Thanks for your order. I believe you have now downloaded the book, but don't forget to download the resources too - you'll need them to work through the exercises in the book. I hope you find the book useful - AppGameKit is a great tool for creating apps and
an easy way into "proper" programming if that is of interest.
For anyone else that is ordering, please remember as it says on the ordering page, we reply to your orders manually so it may be a few hours before we email you the details of how to download the book(s). A bit longer if we happen to be asleep when a purchase order arrives!
Also, very occasionally, our emails end up in people's spam folder so always look there if you don't seem to have had a reply from us.
I had to disable the alistair@ address for the moment since I was having problems with that address but myself or Virginia always reply to sales@ emails too.
