MS word error message while trying to edit the document.

There is a strange error message which I receive when I am using my MS Word 2003 on a Windows Vista Ultimate machine. I have English version of MS Office installed on my machine.
I create a document using MS Word, save it in a particular location on my hard drive. But when I try to do any modification in the document which I have already saved, I get an error message
“The list of common French (France) Auto Corrections is not available. This feature is not currently installed. Would you like to install it now?
I do not remember making any changes in my language , neither would I want to disable the Auto Correct features of English. Please help me to find a way out of this annoying error message.
