Retrieving my old Adobe Flash CS6 file

I used to have a Adobe Flash CS6 and animated. When Animate CC came out, I animated there. I supposed to "save as" the file. But I animated back in CS6 in the same file. Strangly, when I opened in Animate CC, the file somehow changes back to the old saved file version of animation before the final result. I couldn't open back my same old "saved" file. I urgently need an Adobe Flash CS6 or CS5 software to retrive my old file and "save as" to the new file for Animate CC.

Here are my old SWF file and Animate File (but the file is big to attach, I'll show you). Even snapshots I caught evidences.

PLEASE HELP ME!!!
