I have read and followed any applicable solutions in the following articles:
http://support.microsoft.com/kb/938810 (Information about certain file formats that are blocked after you install Office 2003 Service Pack 3)
http://support.microsoft.com/kb/922849 (You receive an error message when you try to open or to save a file type that was blocked by your registry policy settings in Word 2007 or in Word 2003)

However, I am still unable to access Lotus 123 documents from Excel 2k3 SP3. Note that when I attempted to create HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\12.0\Word\Security\FileOpenBlock, I had to manually populate everything under "Microsoft". This seems odd to me. Apparently this key can be redirected from HKEY_CURRENT_USER\Software\Microsoft\Office\11.0\Common, but there was nothing applicable under this key. I created the entries there too for good measure, but I am still blocked.
Any idea on how I can regain access to my Lotus documents? Thanks.
