"sfc /scannow" functionality and CBS Log

So, i'm having hard time with Bad Company 2 Game causing lock-ups and freezes. One of the most helpful thing to do is to type "sfc /scannow" in cmd, let OS fix files, that need fix and everything should work. Yes, but when i run this command, i got message, that corrupted files are found, but they can't be fix. And there is a log. What to do, is the question?

Thanks in advance.

Here is the log, hope the site is accessible - http://store4.data.bg/spooo/cbs.txt
