A couple weeks ago, using fireworks cs5.1, I opened a file I'd been working on the day prior to find that a good majority of pages were completely gone without a trace. I was unable to figure out the issue quickly enough, so I rolled back to fireworks cs5, redid the work I lost, and it has been working (saving/opening complete files) without issue… until today. Same problem. I save a file without issue (no errors, no warnings come up), quit fireworks, launch fireworks, open file, and a bunch of pages and even some random layers from the pages that remain are missing. What in the world could be causing this?
Same thing just happened to me, today. Although I did get an error message when I tried to save. This happens every once in a while for me with FW. But, I had successfully saved a few minutes earlier, so I just quit and started up FW again, expecting I would only have a few minutes of re-work to do.
More than half the objects from layers are missing, throughout the file, including portions of document symbols, buttons, etc. A complete disaster, many, many hours of work to re-do. Luckily I had started saving the file under a new file name a week earlier, so I have SOME content to start from.
I called Adobe Support. They said it is a known issue, and they are working on it. So, nothing we can do at this point.
From now on I'm going to save under a new file name once in a while, to avoid having this happen again.
