I have recently learned Adobe InMarket is shutting down on August 31, 2011. As a result, Sparkbooth will no longer be sold through Adobe after the end of August. According to Adobe:
If users have installed and paid for your application before August 31, 2011, then these users can continue to use the application even after the Adobe AIR Marketplace is shut down. If your application was using try and buy, then applications can be tried or purchased on or before August 31, 2011. Applications cannot be purchased after August 31, 2011.
If you purchased Sparkbooth, it will continue to run after August 31, 2011. Sparkbooth will be migrated to a new purchase and licensing system before this deadline. When the migration is complete, everyone who has purchased Sparkbooth and Sparkbooth Party Edition will be emailed new license keys to use with the new license system.
One benefit of the new licensing system is I can now provide upgrade pricing. Everyone who purchased Sparkbooth Party Edition on or after November 1, 2010 will be automatically upgraded to Sparkbooth 3. Everyone who purchased Sparkbooth Party Edition before November 2010 will have an upgrade path available. Details to come, so please stay tuned.
