I have paid for the program, but why is it still showing as unregistered?
1. Firstly you need to make sure that you have activated the program with your licensed e-mail and registration code. Here are the ways for you to check. Launch the software, go to the top menu, choose Help > Register. After registration, the program will be registered as a full version.
2. If you want to remove the limitation of the trial version, such as watermark. You need to convert your original file again via the full version.
3. If you are asked to register it again when you use the program next time, you need to follow the advice below.
Make sure you use the admin account to log in.
