I wanted to work on my animation today, but when I opened the file, scene1 (with all my work in it) was deleted and replaced with an empty scene2 although the file was still 150mb. Fortunately I still had an older version and only lost about 5 seconds of animation. I also had an .SWF file with the last 5 seconds still in it. I put the last 5 seconds from the .SWF file in the older version as an .MP4, but when I saved the file under a different name, closed and reopened the "fixed" file, I got another error telling me it couldn't open the file. Is there something going on with Adobe Animate I should be aware of? Is there also a way I can recover an old save from Animate that still has scene1? I should also add, I'm currently working on a computer with Adobe Animate 2019 on it. The computer is quite old and the newest version isn't compatible with it.
