I have recently purchased a paid license to upgrade from an eval license. According to one set of instructions I found on support site, I am supposed to receive a new license file as soon as I register, but I have not received it. According to another set of instructions I should seach for a binary activate on my Linux system and run it -- I searched and could not find it.
And just to vent my frustration -- I have never had such hard time navigating a support system. It seems to have been designed by aliens.
