You're still not giving enough details for any kind of diagnosis. "Won't work" is such a vague phrase. Maybe it would help to go through the motions, and write down each step, what you do, what is supposed to happen, and then exactly what does or does not happen. Is it just certain files or figures that won't load? Will any figures or props load at all? When did this problem first start? What did you do just before things stopped working? I used to work tech support. If a customer called with the vague symptoms you mentioned, I'd let them know how much I wanted to help, but I'd explain it was impossible without further info. It's like taking your car to a mechanic and saying "I don't know what's wrong, but why don't you fix it?!"
