Corrupted file, file doesn't work anymore

[Jestemzpolski]

Hello, my issue is...
I making presentation and i wrote file in .odp file format, when making presentation few times i was saved my file, after few hours Open Office closed (error), after reopening OO program trying recover file, after that my file doesnt work. I think OO recovery overwriting this file. Is there any hope to recover my file?
I attached my file.

I regret that there is no hope of recovering anything from that file. Try the suggestions in [Tutorial] How to find and un-delete AOO temporary files; you may be able to recover something that way. Do that as soon as possible.

File is much too small to contain any useful information. A minimal OO file is about 6 KB.

I have in any case checked the file; nothing there.
