Yes I was able to get to this file just pasting full path to folder in adress line. But right click on the file to don allow to see and edit permissions. There were written that just to delete this file will allow to launch new such configuration file after restart of computer but it did not happen. And my PC have just one account and it is labeled as administrator despite have another name. Maybe I need to put strictly Administrator in appropriate menu to Turn off the pc - I just checked just this account after clicking Change User. Maybe in safe mode I can do something? If not - how to solve it? Reinstall the word or manually edit data.dat but when I open it there is some unknown characters?
