repair an otbm file

[YKA]

¿Is there a way to repair an otbm file? Damaged after shutdown of restart, maybe. Here original file, i am talking about,I was mapping a replica in venorean style now the file can't be open in editor, its not a valid OTBM file or it does not exist.
map
black-knight-villa´´7´7.otbm
house
black-knight-villa´´7´7-house.xml
spawn
black-knight-villa´´7´7-spawn.xml
pd: Which is the good web antivirus scan(?)
