"The input file could not be found"

Dear Friends, I could not find the answer to my problem in FAQs.

My MiKTeX (Windows 10, 64 bit) suddenly lost ability to see input file. 
Reinstallation did not help. Could you please help?

Alexandre

<<<ERROR MESSAGE:

Command Line:   texify.exe --pdf 
--tex-option=--interaction=errorstopmode --tex-option=--synctex=-1

Sorry, but texify did not succeed for the following reason:

   The input file could not be found.

The log file hopefully contains the information to get MiKTeX going again:

   C:/Users/AB/AppData/Local/MiKTeX/2.9/miktex/log/texify.log

You may want to visit the MiKTeX project page, if you need help.
