Lost Files Adobe Express

I have been working on building currciulum guides for the upcoming year with adobe Express.  Last week all my files disappeared.  I tried to get help but becuase I am using my school teacher account I have to go through an admin.  However, I have no idea who the administartor for the Adobe programs are andd no one at district office seems to know who the admin is and I have no way to find out.  I am hoping that someone can help me recover my lost files as I am in despearte need to finish this curriculum and it was hours worth of files that was lost. I tried every suggested method in the community chats and still no success.  ADOBE PLease help!
