Either you have accidentally moved/deleted it, or the file has been corrupted. But it's strange that the system restore cannot restore it... Have you checked the recycle bin etc.? It might be one of those silly things where it's just been sitting somewhere the whole time. If this doesn't work then I suggest ringing a technician to see if he can recover the file...
Try this go to start when that pops up there will be at bottom an area that says search programs and files. Type in information and hit search.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
