Problem activating license key on version 3.3.4

[TCWT]

I paid $40 to renew support last week. After entering the license key, it shows an error:

There was an error contacting the license server, please try again later

I've tried everyday for the past 5 days. I suspect the activation server address in the code have changed since my board is quite old.

Version 3.x is not supported anymore, and the old license activation URL for it doesn't work as you've already found out.

The license key at this point is only valid for the 4.x version.
