This will upgrade your current version to our latest version by downloading the new file. You will need to run the new mmsetup.exe file and install it over your existing program. This way your music database will stay intact.
To insure that your system configuration is optimized for the new version, you should delete your mmcd.ini file before restarting the program. You can also do this by going to Recorder/OPT/Advanced Options and click on Auto Configure. When you re-start the program, it will reconfigure itself.
Updates are free and do not require a new key.
