We currently offer free upgrades for Monitor Brightness Switch. You can upgrade your copy to the newest version without any charge.
In most cases, your registration code (license key) will be automatically accepted by the new version, unless you have a very old code. If your registration needs to be updated, please contact us with the following information:
We need the information to locate your order in our database. You do not need to provide them all. Normally we will be able to locate the order and verify your ownership with just your email address - provided that it matches the email address of your order in our database, i.e. you used that email when you placed the order.
We must verify your ownership of the license(s), so please send a message to us from the original email address. You can ask us to update your email in our database if you want, but first please send a message from your old email address.
If you have lost control of your old email address, please provide us with as much information as possible to verify your ownership (physical address, phone number, etc.).
