I've posted a new build for Subscription Tools in the downloads section (members only).

New Functionality Includes:-

• Multiple Subscriptions! Activated by checking the "Multiple Subscriptions?" checkbox in View Options. This will allow a subscriber to subscribe to more then one plan on your site at one time.
• Restructured the view options page for better readability.

Fixed Bugs Include:-

• "Is Active?" now works as expected on each plan.
• Handled a redirect exception that was appearing in some event logs.
• Localization Fixes ("You Must Select A Plan", "You Must Select A Processor", "No Plans Message", "Day/Month/Week/Year" and the register message)

Thanks again for all your feedback!
