Hi - I am using Office 2003 on XP OS. I downloaded the Office 2007 compatibility pack months ago and it worked great. Then it stopped converting at some point. Now, when I try to open a .docx, Word says the file was created in a newer version and asks if I'd like to download the compatibility pack. I've removed the pack, re-downloaded it and it still doesn't work. Each time Word prompts me, I try to download it again. It shows as a successful install. I have all my high priority updates, etc. I haven't had an opportunity to test PowerPoint, but Excel works and handles the file conversion just fine. Any idea what might be happening with Word?
