Can't play recorded call in OLG g3 - Android - Galaxy Call Recorded

[avi123]

Hello,
There are some calls that were recorded by Galaxy Call Recorder in my Android OLG g3. I played them previously and it was OK. Suddenly there is an error message "can't play the track". I didn't do any changes or downloads. So I tried to open it with another players and still I can't play. Were the records damaged? How can I play them?

Thanks a lot
