Word 2013 says "file is not available"

[dum]

Guys, I got brand new problem with Word 2013. Please, consult me if you know what it can be.




I have Office 2013 on the Windows 7 x64 partition. I have not used it there, but now I tried and any time I try to open DOC or DOCX file it says: "The file <name> is not available". It cannot open even files, which were just saved by the same copy of Word. What can it be? How can I fix it?



I have googled the problem already and found very few information. The "solution" with removing three checkboxes in the Trust Center I already tried. Does not helped. Help please!
