Newer version

I have SmartFTP v4.0.1072.0 and the updater says the newest version is 4.0.1222.0. May I update for free or will I have to pay for the update?

You can check the maintenance expiration date in the Customer Area: https://www.smartftp.com/customer/

I don't know how to find the serial number. I did find this in the About window, does that mean maintenance ended in 2010? I thought updates were free until a new major update like version 5.

Yes your maintenance (upgrades and support) has ended in 2010. You can resend your license key/serial at:
