I'm a Graphic Designer at a Design studio who deals mainly with print. However recently one of our client has given us the task of transforming one of their publication to a simple interactive PDF (ie linking the pages to the content) that can be used on the web. Linking pages works well. When reopening after saving the PDF there appears to be missing text on some of the pages. I've checked the original file (created in InDesign CS—Mac. G5)—the fonts appears to be fine.
PLEASE help me resolve this problem.

Thanks
JL
