Fixing Spell Checker MS Office 2007

RUN:regedit.exe
GO TO:HKEY_CURRENT_USER\Software\Microsoft\Shared Tools\Proofing Tools\1.0\Override\en-US
THEN:I had 2 entries (DLL and LEX) pointing to non-existing files.
Rename these to oldDLL and oldLEX.
After this change all Spell Checking worked normal again.
