Thank you for your comments. As detailed in the link below, Fusion 4 orders within 30 days of the Fusion 5 launch (July 8th) are eligible for a free upgrade to Suitcase Fusion 5. The most recent purchase I have for you is from September 2012, which is outside the eligible grace period.
While we understand your frustration, we have to continually develop our products to keep abreast with the various operating system and application advances that happen during the product life cycle, all which require significant involvement from Development. The software/hardware lifecycle for most technology is on average 12-18 months.
Since we support so many Adobe applications – InDesign, Illustrator, Photoshop, & InCopy – we have to build plug-ins and panels that support all of the Creative Cloud versions of these products, which were rolled into the release of Suitcase Fusion 5.
As a registered user of Suitcase Fusion 4, you do have the opportunity to upgrade to Suitcase Fusion 5 for 50% off the full version price.
We apologize for the inconvenience.
