When you get your key file, simply move it to your installation folder for SD, usually the SD folder on your C: drive. SD will be unrestricted when used with your callsign - including any country identifier changes. When the key file is not present, or if SD is used with an unrelated call, it runs in demo mode - the word "DEMO" appears after the contest name at the lower right of the logging screen, and logging is delayed after 30 QSOs.

When the word DEMO is not present, you can be sure that SD will not slow down.

The key file is a standard ASCII text file with 57 numeric digits. You should both print and backup this file, so that you can recreate it when necessary. If it is edited for any reason, it will no longer work.
