I am using fireworks with a new macbook pro retina with a SSD drive. I cannot export an image -- I get Could Not Save File -- File not Found error.
Drive is otherwise acting normally. I reinstalled fireworks -- no help.
Despite the error message, are you able to export the image?
This sounds like a problem that's been reported by users of the new Mountain Lion OS:
Thank you very much ... that seems to be what's happening.
