The file would not open in Fireworks due to incorrect image paths. The image paths are corrected in dreamweaver and saved. The file now returns "Could not open file. Unknown file type."
So, then I made the same corrections with a text editor and saved the file. Same error when fireworks tries to open it.
in way over my head!
I've had that happen too. What worked for me was shutting FW down and rebooting my machine.
