I downloaded the student edition of SolidWorks from Solidworks.com/sek.  I fill in my information and download the installer.  I unpack the files and the installer starts.  Then it gets to the screen which asks for the serial number.  The box labeled 'SolidWorks Standard, Professional, Premium or SolidNetWork License' is checked and the serial number has been filled in for me.  I click next, and I get the warning 'Your serial number does not entitle you to SolidWorks 2014'.  How do I get this to work?  I just uninstalled my previous version of SW in order to install this per the instructions so now I have nothing to work with. 

Thanks in advance for your help.
