I have a slew of maps that were created by zip code in MapPoint 2004. When I try to open them, I get a message that says the format is no longer supported and to search the help files for more information. I can't find anything that tells me how to convert to the new (2011) format. Does anyone have any suggestions on how this may be done, other than to re-key in every one of the map files?
Thank you for any help.
