When I upgrade from MacGAMUT 2003 to MacGAMUT 6, will I lose my records of everything I did on the older version of the software?
No, all your records will be preserved and transferred to the new software version. MacGAMUT 6 will create a new startMG6.mgs file, picking up your name, statistics, and presets files from your start2003.mgs file. From then on, all you have to do is remember to start from your new startMG6.mgs file instead of your old start2003.mgs file!
