Can't play or extract specific custom scenario

hello. I have a campaign file that I made about 10 years ago and I tried to extract scenarios from the file but I failed. I attach the file below.

https://drive.google.com/open?id=17ouVhJlsKm4G5V-VtsDjSBqs-bv40V_k

This campaign includes 6 scenarios and I think the last scenario was corrupted because when I try to play that scenario, the game crushes immediately in 1.0c, and nothing happens except 'bad string length' message in HD edition. (other 5 scenarios works well)

I also tried using "Campaign Manager" program and other scenarios I made were extracted well but this file didn't work at all with 'stream read error' message. and when I tried to modify in HD edition, file error 23 occurs and I couldn't load all the scenarios. (this error seems to language problem)

Can I extract the last scneario from this file? (or just play it) and is there any problems because this campaign wasn't made in English? (the scenario titles are not English)
