After trying to open Draftsight, it says "Xml error: unexpected end of file, line = 12, column = 1 while loading C:\\Users\\..." and when i say okay it crashes. It's been 2 days and I can not use it. 

A day before this happened, I was being able to use it before lunch but after lunch, suddenly every file I tried to open said that file needs recovery (those files still work on other computers just fine), and when i restarted the computer this happened.

Can anyone help me?
