After many permutations of the serial # I did actually submit the correct number and am now running 9.05 under win 10 correctly.
Thanks for your help!

I do not have the original email; however, I have tried of my name & email address. Cannot unlock.
I have a disk for the TMG 9.0 with a serial number, and the serial number for the downloaded upgrade 9.05.
I tried both numbers, still same problem.
I just upgraded to Windows 10 and my TMG9.05 says I have an Expired trial version. When I "unlock to the full version now" with the correct serial number I get the "Registration data is invalid" response. I have I have done the complete uninstall & reinstalled with the lastest installer & run as an admin, but still get the same response.
Please help.
