I'm having the same problem Javier is having. MapPoint 2004 was working just great for me until I upgraded to Office 2003. I can no longer link or add data. I get the same error message "Problem opening file . . . " It is the same error message whether I use my files created new with Excel or the sample files which come with the MapPoint 2004 CD. I've tried making tab, text, and csv files all to no avail.

I'm dead in the water right now
