If you had a previous version of Acrobat that came bundled with the LiveCycle Designer you are entitled to a free upgrade. Information on how to obtain the free upgrade is available here - http://helpx.adobe.com/x-productkb/policy-pricing/upgrade-livecycle-designer-acrobat-xi.ht ml.
Hope that helps.
Jeff - thanks for the response. I don't seem to qualify - even hough I've had Acrobat Pro for years with the Creative / Web Suites. That doesn't seem to be an option. This is just crazy. Why would this product NOT be part of the Cloud subscription is very frustrating.
Nothing but a money grab by Adobe. Shameful. I'm just going to export or screenshot as an image and load into Acrobat/InDesign/Illustrator.
Sometimes you can save the document in rich text format (rtf) and then save it again as a PDF and that will allow you to edit it.
