InDesign Server Trial not Licensing

Hi

I get an error when trying to use the InDesign Server Trial. Error below from what was typed into CMD.

C:\Users\Administrator>cd C:\Program Files\Adobe\Adobe InDesign CS6 Server x64

C:\Program Files\Adobe\Adobe InDesign CS6 Server x64>InDesignServer

05/17/12 12:15:39 ERROR [server] Adobe InDesign Server is not properly licensed

and will now quit.

Thanks in advanced
