Object Library Items are disabled/grey... Why?




I am using Adobe Livecycle Designer ES.

I'm working on making an interactive form however when I open up the PDF file (original file) into Livecycle Designer several of my objects in my library are grayed out and disabled. Most notably, the Static Text box tool, Rectangle Tool, Subforms, Tables and Images are all disabled.

When I start a new document these are all available and function properly. It is only when I open this specific PDF file to work on does the wierdness start.

I'd love to know why this is happening. Any advice would be useful.

Thank you,

Jesse Burke
