I've been using Art Rage for a couple of years now and the program has not given me any problems until now. I use a Macbook Pro. I spent three days developing a painting when suddenly, Art Rage crashed. I had been saving the ptg file regularly, but when I tried to open the painting I got a "generic failure" message, and the file would not open. The ptg file is present on my computer, but it is only 40Kb in size, while the original painting I was working on is at least 150Mb in size. Is there any way to recover this painting? I hate to lose 3 days of work.
