When I cut and paste the serial number into the activation bar in the Age of Wonders 3 autoplayer, it simply spits the number back out, claiming its an invalid serial number.


Edit: NVM, fixed it. Turned out that cutting and pasting it was the problem. It made it so there was an invisible space before the first letter in the code, which in turn bumped off the last letter from the activation bar.

Happened to me too because I copied an empty character and then the launcher deleted the last letter of the key. Make sure you copy no extra characters.
