For the second time it has happened. My computer crashed while I was writing my notes in the classroom. When I restarted the machine and I tried to open the document, it was unreadable. I guess it's not a problem of "recovery" since sometimes the program crashes and the documents remain ok. The question is that I've lost the entire document, several pages of notes that I started in the beginning of the semester.
I send the document as an annex for you to try to open it. I would like to recover even a fraction of what I had but right now all that appears is ############## in the entire document. I believe it is the same document because the number of the pages is similar. But when I try to open it it asks me for some ASCII code and I just say OK and... well, give it a try, you'll see!
I would be deeply thankful for anyone that could help be to solve this problem. I have another document under the same circumstances. Only this time, no backup for the previous lessons...

Best Regards.
