Some things that may or may not be relevant:
1. When I open the file it is all hashtags.
2. When i open the laptop i get a recovery box with the file in it. This file seeks to be recovered but I get told that it is 'read only’.It then opens a box that I have no idea what it is, but, when it appears it means that the file I’m trying to open will be a random selection of characters.
3. Other files open up fine.
4. The book file was open when the computer crashed.
5. It had been saved several times this morning before the crash.
6. It is an odt file.

What can I do to recover my work that doesn’t involve me becoming a computer programmer?
Thankyou.
