Not enough memory error

I’m going crazy here. I’m working under XP with Flash 8. The fla file is about 85 MB and has 60 frames with panorama photo’s. Everything went great for months, untill a couple of days ago. I got the following message while publishing to a projector (or a swf):

“Error creating Flash movie. There was not enought memory available.”

But there is enough free memory. I cleared 6GB. There is enough internal memory (2GB) and I have messed around with the virtual memory. But the message keeps popping up.

On the internet I read that it could be a corrupt images. So I put everything in a new fla with mixed results. Sometimes it works and even makes a projector, sometimes (more) it doesn’t. Sometimes copying frames to a new file works, but then Flash crashes, I’m becoming crazy here.

How can you spot with image or file is corrupt? All photo’s in the library look normal. So how do you recognize a corrupt image and how do I get rid of the error?
