Lost my work on updating XD

While working today I found XD had launched a flip feature allowing users to flip images along length, etc. When I updated XD, I lost a lot of work I did in last few months - You can see the work I'm referring to in the published prototype - it will show a game called Bujo. Can you please restore my files to as they were before I updated XD. I've looked everywhere I could think of but can't find the files.
