Can not open Writer on Windows 7

Yesterday I have installed LibreOffice 4.2 Russian. I can open Math, Impress, Calc, Drow, but, when I’m opening Writer it is opened as blank square window. It has working menu up and information down (No. of pages, No. of words/symbols, language, scale, etc.) but it has no field where to put text - it is just white void between menu and information. I cannot see text when I’m typing it but information below shows that I’m putting words and symbols (numbers are changing).

My system: Windows 7 Russian
Notebook Sony Vaio VGN-TT4MRG

A few diagnostic questions:

Are you able to provide a screenshot?

Can you see rulers and scrollbars to the side and top of the window?

What happens when you click ‘File > Close’? Does it revert back to a libreoffice menu?

I suspect that a new document is opening but that the zoom has gone awry.
