Registering Diiva
Register Diiva for US$35, and you get:

Unlimited Use
Registering Diiva is equivalent to "buying" the software. As such, its capabilities are somewhat limited before you register. In particular, you can only use it for 15 minutes at a time, after which the software automatically quits.

Fully Functional Download Queue
In addition, Diiva's download queue is limited to five images while unregistered. Registering removes this limit, allowing you to queue as many images as you like, or even queue all the images in a group with a single menu command.

FREE month of network image previews
When you register Diiva, you'll also get a FREE 30-day trial of our preview service, described below.

Network Image Preview Service
One of Diiva's most impressive features is its ability to instantly contact our preview servers and download previews for images available over the network. When this service is enabled, simply opening a category of pictures causes Diiva to query our servers for previews, automatically download them, and display the previews in the network image list.

After your free trial month of the preview service, you will be automatically billed US$5.00 per month to continue to receive previews. If you do not wish to subscribe to this extra service, you may cancel it at any time after you register by sending email to billing@diiva.com.

Registration Codes
After you register Diiva, the software will automatically unlock itself and no longer be subject to time or download queue limits. Should you need to reinstall the Diiva software, or otherwise remind it of its registered state, you can request a registration code from within the software. (Choose Preferences... under the Edit menu, and click the Registrations tab.) A registration code will be instantly emailed to you, which you can then enter into Diiva.
