Unable to create a new file

[Bables55]

I can't create a new file in the main browser section of the file or in the office menu. When I try to create an empty file in the main browser section of the file, determine the name of the file, nothing shows up. When I'm in the Office menu, I get "Can't create document" just by clicking on the Create menu. I leave the office menu once and go into a different mode. Then I go back to the office menu, no warning appears, a blank box appears momentarily on the list and disappears.

I can edit existing files.
