Error message when entering license

When I enter product code (BK400407EDSTUDENTUNICL) in the installation it gives me an error message. Hovering over the message says "error in license processing please contact ptc license management". And yes I have tried entering the product code manually rather than copying/pasting and it stills gives the error message. And under license summary there are no sources listed. I need this program ASAP, please help!
