Problem with activating a license on SU Podium V2.6

Hi,
It seems like I am not able to properly activate my new SU Podium license. I was wondering if someone knows and can share every step to installing this extension on a MacOS. I have an architecture project due tomorrow, please help me!! Thank you!
