Hi, I am a student  and trying to use the 60 day free trial of solidworks. I go to https://www.solidworks.com/how-to-buy/get-education-trial ,and follow the steps. Once I fill the form and press "Request Download" I get an error that says "Please enter a valid serial number." as shown in the picture attached.
Can someone help me with this?
