In order to use your Campus version or your Temporary License on different computers, you will have to wait 6 hours between using it on either computer. If not, when attempting to use it on the second computer, the following warning will appear:
The maximum number of simultaneous users for this license has been reached.
The waiting time refers to the device, not to the IP address to which you are connected. Therefore, you will have to wait 6 hours to use different computers from the same IP, but you can use the same computer from different IP addresses to continue using your Campus or Temporary version without the 6-hour wait.
