Can't open anymore a GroupShare Project on Trados 2015 SR2

Question

Hello, I was assigned a project on GroupShare by SDL last week. I successfully imported the project and check out all files for translation. I have translated and checked in a first batch of files yesterday. 15mn ago my PC stopped and restarted. When I open again Studio 2015 I couldn't find the project so I went to "OPen project" and tried to open it, but I have the message "An error ocurred while trying to determine the file version" so the project and the file won't open. I've cloed and reopen Studio same issues. 
 If I pass by the desktop and try to open the project directly, I have Studio opening then same kind of message and the project and the files won't open. I've tried to open an old project I've done for SDL 3 weeks ago and it worked fine. 
 Does anyone know how to solve the issue as I have another batch to deliver tomorrow ? 
 Thanks

I finally solved the issue by contacting someone at SDL. I had to make sure that the files already translated + my TM were saved on my desktop, then delete the master project from the desktop. Then I was able to found the project again in GroupShare, extract it and replace the files it contains by the ones already translated. So when I open again the project I had my files as they were before my PC stopped. Only two or three files couldn't be opened because of an issue of "hexadecimal". I have no idea what it means but I will check that later.
