Solidworks Student Activation Transaction Failed

I installed the Student version SolidWorks 2024 on my PC a month ago. After installation, I was presented with an option to activate immediately or try it for 30 days. I chose the second option. Now that the 30 days grace period has ended and when I tried to activate SolidWorks, I got the following message.

Activation transaction failed: Serial number not entitled to SOLIDWORKS 2024. Check that you have entered the correct serial number. For further support, contact your support representative.

 

May I get your advice on the matter.

Thanks
