After receiving a new license code via e-mail, how do we change it in the program?
(The activation menu item is not available due to having entered the original code used.)
Deactivate as meant here (http://bitsum.com/forum/index.php/topic,1982.0.html), then activate again with your new activation code.
Yes, alternatively, if you are the more laid back type - you can wait until the day comes when it says 'enter another activation code'. Either/or ;).
