License key for IntegrationServer4


I have dowloaded the IntegrationServer4.6_SP1_en_US_Unix.jar(Evaluation copy) using username and password supplied by webMethods. But, I did not get the license key for the same. I installed the same by skiping the licese key option while installing and its installed successfully. However,when I see the Adminstrator page on IE , its showing your licese key will expire in 30 minutes.

Can anybody help me where can I get the license key?

Thanks in advance,
