Import of History from FDM 3 and FDM 5.0 is turned off
Integration with Internet Explorer is not available
Making backups is not necessary as long as you DO NOT uninstall the previous versions you were using. FDM 5.1 Beta DOES NOT interfere with any of the FDM 3.9.* service files (.sav) nor does it import settings/downloads from older FDM verions.
