There are no separate trial and registered versions of CMDebug. Without registration, a trial version is fully functional for 30 days of use.
At any time you can apply your current personal registration information to a trial version in order to turn it into a registered product. You can view your registration info with the Help/About menu entry in CMDebug.
When you purchase a new or upgrade copy of CMDebug, you will receive an email with your name and registration key. Start CMDebug, click on the Help menu entry and then Register. Enter the registration information exactly as you received it in the email. Remember to save your registration key in a safe place in case you need to reinstall. If you have lost your registration key, you can request a replacement by contacting JP Software at email@example.com.
If you need to remove your CMDebug registration from a computer, click on the Help menu entry and then Register. Enter the activation key you used to register CMDebug and then click on the Unregister button.
