After successfully ordering, you will receive a registration code to unlock the trial version. Please run MP3 CD Converter and input the registration name and code in the registering dialog from menu "Help->Register...".

NOTE: Please copy and paste the registration name and code to the registration dialog and DON'T type it manually because it's difficult to distinguish the letter "l" ( lower case of "L") from "1" (one) and "o" from "0" (zero), etc.
