I have the same problem... have work done in Fireworks and need to update files... Fireworks is crashing every second...
I've managed to get Fireworks to open by uninstalling and re-installing through creative cloud desktop app. It took a couple of attempts and I made sure I had updated everything on my Mac.
My files are opening but there's now a definite fear that something else might break soon. Fingers crossed...
We just need trusty ol' Fireworks to hold out until the arrival of Project Comet next year.
Wow! I did un-install, and installed again, and at least let me open the file... but, when I do 2 or 3 things, the crashes.
Waht is Project Comet
Project Comet is Adobe's upcoming mobile and web prototyping software. However, it is NOT an alternative to Fireworks. You will require Photoshop and Illustrator (or other applications) to prepare assets for use in Comet.
There is a fair chance that Comet will die before it matures: same thing happened to Edge Animate and a number of other web applications Adobe introduced a couple of years ago. Adobe is struggling to keep up with the web development and design industry.
