How do I activate my student license?

I received an SDK-ID and serial number from my school yesterday with the place to download to Solidworks. I went through all the installation and input the serial number during. Everything installed just fine but when I go to open the program it says it can not obtain a license file then underneath says it cannot find a license file.

What does this mean? I input the license in and even double checked it through the set up again. How do I fix this so I can use Solidworks for my class?
