I think you may be in the wrong forum. This forum is for Adobe InDesign. It's a desktop application that is used to layout publications. It sounds like you have something completely different.
What kind of computer were you running Adobe Export PDF software on, a Mac or a Windows computer? Were you also storing your files on that computer?
