I forgot to tell you that a friend suggested me a pc program to recover lost files and etc. the program it's called Pandora recovery. Here is a link from softonic:

I think it's a freeware. I used it and I recovered many things and also half of a word document I was working on! Imagine that! I almost jumped to the sky, I even hugged my dog while spinning XD yes, poor dog.

Well, hope it helps you as much as it can. First see if it has 2 versions: one for microsoft and one from mac, since I don't now what laptop or desktop you're using. Yes, kind of a nerd, that I am buuuut that knowledge saved my life so many times XD

Cheers
