I am running Windows 8.1 which I installed over Windows 7. It has worked fine for several months. Recently an email in Outlook 2007 apparently deleted the .pst file which caused Outlook to not start. I have successfully reinstalled the .pst file and Outlook works fine.

Since then when I log on and start Windows 8.1, I get the message: Fatal Error. No language file was found. However Windows starts up fine and operates fine. Should I do anything?

check at event viewer for detail error log, I don't think this is windows error, maybe caused by 3rd party software

I suggest perform clean boot

Hi,

I suggest you to restore the system back to the point when it work fine.

Considering that virus or corrupted files caused this issue.

To restore your PC to an earlier point in time

1. Swipe in from the right edge of the screen, and then tap Search.
   (If you're using a mouse, point to the upper-right corner of the screen, move the mouse pointer down, and then clickSearch.)

2. Enter Control Panel in the search box, and tap or click Control Panel.

3. Enter Recovery in the Control Panel search box, and then tap or click Recovery.

4. Tap or click Open System Restore, and then follow the instructions.
