I was talking to someone and i forgot the log file opened

Then a message appeard "the file is in use" or something like that ,
After that a new log file was created for that contact and i lost the old log file
I recovered the old log file using some recovery software called Recuva
But i cant open it ,its damaged or i don't know ???
When i try to open the log file the page is blank
Sometimes i get this Dialog
Open ,Save ,Cancel
