If you lost your license code (registration code/license key) after purchase, please take it easy, things will work out eventually. Here are three solutions to fix it as follows.
Please try to check your license code again from your licensed email (registered email), which is the email address you used when placing the order.
Confirm Your Licensed Email
Check and copy your license code under the "License key for unlocking the product".
Check License Code via Email
You can also check your license code on the payment platform - MyCommerce. Here please be noted that if you have completed the order for a long time, you can't directly check the license code on the "Order Complete" page of the payment platform, but you can always check your license code on MyCommerce.
Check License Code via the Payment Platform
If you can't find your license code from the payment platform (MyCommerce) and your licensed email, please contact us for further assistance via email: firstname.lastname@example.org.
Please enclose your order information (such as order ID, email address, name you used when you purchased, etc.), which will help us exactly find your order in our database and send you the license code again. Please remember to back up the license code after you receive it.
