I am posting a new discussion of this since I couldn't find an answer for this for a Windows computer. I am using Windows 8.1 and Flash CS6 using the Creative Cloud Application.
Whenever I try to save a .fla document it gives an error saying it "cannot save the document as [filename] try changing the filename or file location".
I do work over a network but have been saving the file to my desktop and moving it back to my network file when I'm done editing it. But now its happening even with local files on my desktop. Is anyone else having this issue or found a fix?
