You may have powered off your computer (or hibernated/slept it) before the hardware/software write buffers had flushed to disk.
The chances are minute that you will recover anything from the existing file.
To try and recover your file, you should look in the backup and temporary directories pointed to by /Tools /Options /OpenOffice : Paths. Rename any files in those to type .odt (or whatever file type you were using) and see if they contain your data. Download Recuva or PhotoRec (only one needed) and let it do an indepth recovery of deleted files on your computer. You may get a file containing some or all of your data (or not). Pending running Recuva/PhotoRec make as little use of your computer as possible to avoid overwriting any deleted file.
