We recently posted an update to the Appstore SDK here.

This update introduces two material changes. These are:

• Unity3D plugin: Using a namespaced version MiniJSON to avoid name conflicts.
• AdobeAir Plugin: Fixed bug in actionscript when parsing a Date object as type ‘int’ would return an incorrect time.

Please download the latest SDK to get the latest UNITY and Adobe plug-ins and remove the old plug-ins.
