Indesgin files corrupt

Hi all,

My hdd which i had all my indesign projects has failed.

I was able to recover most of my files, some indesign files working but others don't

I'm getting message: "Adobe Indesign may not support the file format, a plug-in that supports the file format may be missing, or the file may be open in another application"

Can anyone please help?

Regards,

Stavros
