Unable to reopen my Project (almost completed )- SDL Trados 2015. Error Message : UNE ERREUR S'EST PRODUITE LORS DE LA TENTATIVE D'IDENTIFICATION DE LA VERSION DU FICHIER.

Hello,

My version is Studio 2015 and my detailed problem is as follows :

I worked on a big document for about three weeks and was at the level of 86% done.

Yesterday, I tried to open it, but I got the message : UNE ERREUR S'EST PRODUITE LORS DE LA TENTATIVE D'IDENTIFICATION DE LA VERSION DU FICHIER.

Then I tried to use some suggested solutions, such as opening a new project on base of the target language saved vesrion (SDL XLIFF) by chosing (analyse only) in preparation step so that I keep the already done job. It is then where I got the other error message : 'is an unexpected token. The expected token is '='. Line 120362  position 952699.

Your help is highly appreciated.

Even if it would be possible I send the blocked document so that you help me opening it.

Best regards.
