Changes has been done to the map-database.
The new name of the databse-file is ut2k3mapsv2.dat

Changes are also done in UT2k3Mi.ini

Just to be safe, you should make a backup of UT2k3Mi.ini and ut2k3maps.dat before you launch the program for the first time.
None of your UT2k3-files will be damage, but you will loose information about installed maps if anything should go wrong.
