When I attempt to open a word document, I get a error message

Hey guys !

When I attempt to open a word document, I get a error message :

Word failed reading from this file. Please restore the network connection or replace floppy disk and retry.

I'm left with 2 options - retry and cancel.

I see my text in teh background, however I can't access it because the popup box is in the way.

I'm running it off a local hard drive.

Does anyone know how I can repair this ? It's a very important document.

Thanks.
