I just bought a new macbook pro and transferred all my CS3 design files to the new machine. I then began the trial version of Adobe Creative Cloud and downloaded the latest version of Fireworks. When I opened fireworks it stated that the file was created using a legacy program, which it was, and that I needed to update the text. I clicked update and began working on the file, making a few changes. However, when i went to save the file, it said it could not save the file. I reopened the file and no changes were saved. I then made the changes again and this time it worked. Am I going to have this problem with every file that I created in CS3? How do I fix this permanently for all files?
