I would also consider running chkdsk /r on the C: drive and running the sfc /scannow command (to attempt to overcome possible file corruption).
To run chkdsk /r: Start/Run...type chkdsk /r (with space between k and /), hit Enter or OK. When screen prompts for answer, type Y and hit Enter/OK. Reboot system and let chkdsk /r run to completion, system will reboot when command is complete.
