I have bought my Warband on Taleworlds one week ago. Then I have tried manual activation, because I want that "longer key for offline activation" for later use. But I got everytime same answer:
The entered Serial Number is invalid. Please try again.
I have already several times tired this web site: http://act.taleworlds.com/manual.php
as well. So than I have tried direct activation and it worked fine, without any problem.
So my problem is that I am not able to get "longer key for offline activation" from manual activation but i can use the same serial number to direct activation. I do not understand how is this possible
