Hi steak :)
It appears that only one file is corrupted, and it's a known one under Windows 8 and 8.1. SFCFix should take care of it. Follow the instructions below please.
SFCFix - Run Only
Follow the instructions below to download and execute SFCFix, and provide the log.
- Download SFCFix and move the executable on your Desktop;
- Right-click on SFCFix.exe and select Run as Administrator;
- Follow the instructions displayed in the console;
- On completion, a log will open in Notepad. Copy and paste the content of that log in your next reply;
Note: The log (SFCFix.txt) will be created in the same directory where SFCFix is run if it doesn't open automatically on completion.
