Project disappeared from the project list!

Question

Hello all, 
 
 I was working on a project within Trados 2015 and suddenly my system got unresponsive, so I had to do a hard reset. The problem now is that the project I was working on disappeared from the project list. When I try to open the project file through the "Open project" button on the ribbon, I get an error message saying an error has occurred when trying to determine the file version. Any ideas? 
 
 Any help would be greatly appreciated!

Well, I finally opened the project package, loaded the old TM and used the pretranslate function to load the changes I had done to the project. Fortunately it worked with some minor issues.
