What shall I do if the registration code is invalid?

1. Make sure the software you are registering is the software you've purchased.

2. You upgraded the software, but the old registration code will not be accepted by the new version.
The registration code you received from us is only valid for the version when you placed the order. If the software is upgraded, please go to our Support Center and retrieve the latest Download URL and the registration code.

3. Wrong spelling of your reg name or reg code.
Since the license code is letter-sensitive, please COPY and PASTE the code. And don't add any blank before or after it.

4. If the above is all correct, you still could not register the program successfully, please contact us at order@videoconverterfactory.com
