a) use [b][i]Previous Versions[/i][/b] (W7 and later) to recover previous versions of the file ;
b) recover your file as it was when you last opened or saved it, or as it was when it was last saved with AutoRecovery;
c) find previous versions of the file in the folder it is located in, but which have since been deleted;
d) un-delete the temporary files AOO wrote while you were editing the file, and then deleted. This will recover your file as it was when you last opened or you last saved it.
If your file is opening as ###, it is damaged - possibly because of over-hasty power off of the computer before the internal buffers in the hard drive had written to disk. If it is asking for selection of an ASCII filter, it is also most likely damaged and experience shows that you should not waste any time with your existing file - it will have no usable content. Concentrate on the recovery methods outlined in the tutorial.
