For whoever has this problem and hasn't found a solution, here's what I did. I had extra fonts installed in my user font folder (not a lot... maybe 300 or so), and just like you, Word would sit there forever, not going anywhere. So I checked out my user font folder, and what do you know... Office had installed a whole slew of fonts. Took those out, and boom, no hanging problems. I didn't have those there with the previous version of Office, and I haven't missed them since I took them out. Word says that I had a few corrupt fonts when loading, but it still loads fine.
