Serial number expiration help requested

Hello, I'm looking for help with how to renew my serial number. I've had the student edition for less than a year.  I had to factory reset my computer which made me need to re download solid works. It claims my serial number is expired and is unable to be installed. Would anyone know how to receive an updated serial number without repurchasing?

Best regards,

Chloe Plautz
