The Download Lessons feature of Little Reader Touch allows you to download more content online, but sometimes you may encounter an error saying "You are not allowed to make purchases," as shown below:

This particular error comes up especially if your device has Restrictions set to disable In-App Purchases, and you can quickly enable this setting in just a few steps:

1. Open Settings, then go to General and select Restrictions
   
2. In case you have previously enabled restrictions on your device, you will be asked to enter your settings passcode. Otherwise, if you currently have restrictions disabled and you wish to enable them, you will be asked to set a new passcode.
   
3. In the Restrictions screen, go to the Allowed Content section and make sure that "In-App Purchases" is turned ON
   
4. Once you've set your device to allow in-app purchases, restart Little Reader Touch and you should be able to access the Download Lessons feature without any problems!
   

TIP: Disabling In-App Purchases is a good way to prevent accidental purchases made in any of your apps. If you prefer to keep this particular setting, you can simply re-disable In-App Purchases by changing your Settings once you're done downloading additional content for your Little Reader Touch.
