Solidworkds Student Edition Asking me to activate product upon Launch

Hello! 

I downloaded the Solidworks student edition 2025, after obtaining the serial number (license key) and followed all the instructions. However, once I installed and launched the program for the first time, it asked me activate my license. I selected activate over the internet, but it keeps saying 

Activation transaction failed: Serial number not entitled to SOLIDWORKS 2025. Check that you have entered the correct serial number. For further support, contact your support representative. (3/0)

What should I do to fix this problem?
