The game requires a constant internet connection. If you have intermittent Wifi, or if the device decides that it wants to do something else (receive push notifications, check email, etc.), the connection will be interrupted and the patching process will be aborted.
Try a couple of things:
1) Disable Push Notifications and Push Email.
2) Try another Wifi connection, or 3G if you have it if not update ur iphone or ipod and try again
if not contact support at support(at)spacetimestudios.com and tell them the problems u are having
