Version 1.2

From Developer's site.

"System Requirements

To run YAI version 1.4 you will need an Apple Mac running Tiger or Leopard, Apple Mail, iCal and Address Book.

PLEASE NOTE YAI is not compatible with OSX 10.6, Snow Leopard and I have no current plans to develop this software to run in OSX 10.6."

Hi Rob,

Thanks for the review. I have been trying to get in touch with you.

The email address you used for PayPal when purchasing bounced my emails.

If you still have not received your code, contact me again.
