There's a document that I've been working on for about 3 months now.. a few days ago I noticed that it wasn't on the files list when I open MS office..but luckily for me, I could still open it when I minimize the apps.. and now since I cleared apps on the minimize log my document is gone..just like that.. 3 months work😨. All other documents are there. Even ones from a year ago. I've updated MS office but still nothing. How do i fix this????
