You have two issues. The request for entering the serial number is a "feature" of Windows 8 and 10 which removes the registration information regularly. The solution is illustrated in anarticle on my website.
The failure to unlock when you try to do so is another issue. The most common reason for this is entering a current email address rather than the one used when you obtained the serial number. You must enter the email address and name as it appeared when you obtained the serial number. Another reason is using a serial number from another version of TMG.
Hi Joe, I'm sure I'm entering in the right email. Is it the one we get updates sent to or the one we entered on payment? Either way I've tried both but still get an error.
