Office 2007 & Sharepoint 2003 Document Workspace

[Tony]

I created a document in word 2003, created a document workspace with it;
uploaded additional documents to this workspace; then a few days ago,
upgraded to Word 2007.
My question - Word doesn't seem to recognize the current document workspace
- is there a way to re-initialize the document to point to the already
created document workspace, or do i have to create a new one with word 2007
and upload all the other documents? I have two other people sharing the
files with Office 2003.
