Word cannot find the spelling file (Word 2000) (Solved!)

[ChrisGreaves]

I have just spent an unpleasant few minutes copy/pasting and finally Repair-ing my Office 2000 installation only to find that I need not have done.
Perhaps this short post will stick in your mind for the eventually of this happening to you:

The message "Word cannot find the spelling file Mssp3XX.dll or Mssp232.dll" is documented on the Microsoft Site, and had I known that, I'd be 30 minutes up and half a day ahead.
The cause (in my case) was mixed-language settings in a file imported as RTF from my Netbook's Win7 Wordpad.

A quick Ctrl-A; Tools, Language, Set language to a single source fixed the problem.
Grrrrrr!
