Yesterday, I suddenly began having problems with my Fireworks C5. I can't "save as" a file. I'm getting a message that the 'file is locked'. Any changes that I make to text are undone as soon as I move the cursor. Then, when I exit the program, I'm getting a message that the program didn't exit properly and there's a C++ warning. The only changes that I've made to my computer is the last few days has been a Microsoft Windows update. (I'm using Windows 7.)
What am I doing wrong, and what has suddenly haoppened? Any ideas?
