You can fill out a
Support Request, and I can look up your information to see which games you purchased directly from us. If you think you could have used multiple email addresses, you might want to include those in the message area.
The "unidentified developer" message most likely comes from Gatekeeper.
Apple has introduced a new feature called Gatekeeper to help protect Macs from potentially harmful application downloads. By default, Gatekeeper's preferences are set to allow installation of downloaded applications only from identified developers and the Mac App Store. We have not yet completed the process of changing all of our games to versions that will be recognized by Gatekeeper as coming from an identified developer; however, it is safe to install them in Mountain Lion.
To learn more about Gatekeeper and to see how to proceed with the installation of the games, you can refer to Apple's Gatekeeper page on their site:
