Question: Word:mac spell check is not working

my spell check in word 2004 isnt working....but the spell check in my other Microsoft Apps works fine (i.e. Excel, PowerPoint). i clicked the toolbox and it says that the US English Proofing Tools are not installed, where can i find the download to get the proofing tools?

i followed a tutorial that told me to go to EDIT/REPLACE/ and change the formatting to USA and check the grammar box....i did it and still nothing works

can anyone help me? help is appreciated

thanks!
