Restore older sheet music version

Hi,
I created 2 versions of sheet music for the same piece- one in Ukrainian, another phonetically in English. Saved them as 2 separate mscz docs and also exported into pdf files. In PDF they exported fine, but mscz file that supposed to be in English was overwritten by the Ukrainian file. I looked into history of my files and it didn't help. Is there any option to restore that file? I don't wanna write the whole piece once again.
Thanks for all you help :)
