As mentioned try to explain as precisely as possible what happened (how did you save your score, did you get an error message (maybe a silly question) and so on)?
If there wasn't a crash or an error message, did you search for all "mscz" files on your system/storages?
Btw. your English isn't so bad, maybe better than mine ;-).

What does it mean "program started bugging and I lost my partiture"?
Did MuseScore crash? If so, you've to take a look for a backup file: https://musescore.org/en/node/52116.
Or does it mean you get a message, that your score contains corruptions? Then see: https://musescore.org/en/node/54721
Please explain "started bugging" what happens exactly.
Or are you looking for the same score as here: https://musescore.org/en/node/272311?
