|It seems to me that dll file is corrupted, you can try to restore your system to a previous restore point (Your data will not be lost) if that somehow wont work. |
Try and reinstall your computer..
Be sure to backup your important data, by either burning it to a cd/dvd or by copying it to a usb stick or harddrive and turn off your pc before unplugging it, to ensure your data is safe.
Best of luck!
