Microsoft Word Spell Check Issues

My Microsoft Office spell checks stopped to work. I tried all possible methods listed in Microsoft help - like Proofing options in Word, Set Proofing options and so on. But nothing worked except the one below.

1. Go to "Start"->"Run", then type "regedit" and follow the link as below:
"HKEY_CURRENT_USER\Software\Microsoft\Shared Tools\Proofing
Tools\1.0\Override"

2. Remove Override folder.

3. Spell Check will work as its meant to.
