@Chong Jun Ng,

Is this the email you used to request the evaluation license, "191448..............edu.sg"

Are you using your institution’s computer to request the evaluation license? If so, someone in your institution might have already used this computer to run trial licenses for Lumerical in the past. Trials can only be requested once per user and machine.
