Scenarios gone after reinstalling

I was working on 2 big scenarios for Aoe2 DE and I got quite far, but I got bored of it and had to clear up some space on my computer so i uninstalled the game. A few weeks ago I decided to reinstall and start working on my scenarios again to find out they were all gone. I tried restarting my game and checking my files but there was nothing there.

Are my scenarios gone forever or is there still a way to retrieve them?
